Add a special device tree include for MSM8916 on ARM32 that sets up
SMP and cpuidle without PSCI. This is meant for devices with signed
firmware that does not support PSCI and only allows booting ARM32 kernels.

Add the device tree nodes necessary for SMP bring-up and cpuidle
without PSCI on ARM32. The hardware is typically controlled by the
PSCI implementation in the TrustZone firmware and is therefore marked
as status = "reserved" by default (from the device tree specification):

  "Indicates that the device is operational, but should not be used.
   Typically this is used for devices that are controlled by another
   software component, such as platform firmware."

Since this is part of the MSM8916 SoC it should be added to msm8916.dtsi
but in practice these nodes should only get enabled via an extra include
on ARM32.

This is necessary for some devices with signed firmware which is missing
both ARM64 and PSCI support and can therefore only boot ARM32 kernels.

The LTE version of the S4 Mini VE has a NXP PN547, which is supported
by the nxp-nci-i2c driver in mainline. It seems to detect NFC tags
using "nfctool" just fine, although more testing is difficult given
there seem to be very few useful applications making use of the
Linux NFC subsystem. :(

Note that for some reason Samsung decided to connect the I2C pins
to GPIOs where no hardware I2C bus is available, so we need to
fall back to software bit-banging with i2c-gpio.

The Samsung Galaxy S4 Mini Value Edition is an updated version of the
original S4 Mini based on MSM8916. It is similar to the other Samsung
devices based on MSM8916 with only a few minor differences.

The device tree contains initial support for the S4 Mini Value Edition with:
  - UART
  - eMMC/SD card (needs quirk for some reason)
  - Buttons
  - Vibrator
  - WiFi/Bluetooth (WCNSS)
  - USB

Unfortunately, the S4 Mini VE was released with outdated 32-bit only
firmware and never received any update from Samsung. Since the 32-bit
TrustZone firmware is signed there seems to be no way currently to
actually boot this device tree on arm64 Linux at the moment. :(

However, it is possible to use this device tree by compiling an ARM32 kernel
instead. The device tree can be easily built on ARM32 with an #include
and it works really well there. To avoid confusion for others it is still
better to add this device tree on arm64. Otherwise it's easy to forget
to update this one when making some changes that affect all MSM8916 devices.

Maybe someone finds a way to boot ARM64 Linux on this device at some point.
In this case I expect that this device tree can be simply used as-is.

Commit 0f6b380d ("arm64: dts: qcom: apq8016-sbc: Update modem and WiFi
firmware path") added "firmware-name"s to the APQ8016 SBC (DB410c) device
tree to separate the (test key)-signed firmware from other devices.

However, the added names are a bit confusing. The "modem" firmware used by
DB410c is actually a simplified version for APQ8016 that lacks most of the
modem functionality (phone calls, SMS etc) that is available on MSM8916.
Placing it in "qcom/msm8916/modem.mbn" suggests that it supports all
functionality for MSM and not just the reduced functionality for APQ.

Request the firmware from "qcom/apq8016/modem.mbn" instead to clarify this.
Do the same for "wcnss.mbn" for consistency (although the WCNSS firmware
works just fine on MSM8916).

Finally, add a "_sbc" suffix to the WCNSS_qcom_wlan_nv.bin firmware file.
It seems like the nv.bin firmware is somewhat board specific and can
therefore vary a bit from device to device. This makes it more clear
which board it is intended to be used for.

At the moment, longcheer-l8150 is using a dummy extcon-usb-gpio device
that permanently enables USB gadget mode. This workaround allows USB
to work but is actually wrong and confusing. The "vbus-gpio" used there
refers to an unused (floating) GPIO that is pulled up to make
extcon-usb-gpio report USB gadget mode permanently.

Replace this with the new &pm8916_usbin extcon device that actually
reports if an USB cable is attached or not. This allows the USB PHY
to be turned off when there is no USB cable attached and is much
cleaner overall.

At the moment, USB gadget mode on MSM8916 works only with an extcon
device that reports the correct USB mode. This might be because the
USB PHY needs to be configured appropriately.

Unfortunately there is currently no simple approach to get such an
extcon device during early bring-up. The extcon device for USB VBUS
(i.e. gadget/peripheral mode) is typically provided by the charging
driver which is almost always very complex to port.

On pretty much all devices with PM8916, the USB VBUS is also connected
to the PM8916 "USB_IN" pad, no matter if they use the linear charger
integrated into PM8916 or not. The state of this pad can be checked
with the "USBIN_VALID" interrupt of PM8916.

The "qcom,pm8941-misc" binding exists to expose an "usb_vbus" and/or
"usb_id" interrupt from the PMIC as an extcon device.

Add a &pm8916_usbin node to pm8916.dtsi which can be used as simple
extcon device for devices that are currently lacking a proper charger
driver.
