With the IO chain reconfigure fixed, we can now enable the PMIC
scripts for LDP.

Note that at least on my es3.0 based LDP, the UART seems to be
flakey after wake-up events from off-idle and hangs but eventually
continues.
Signed-off-by: Tony Lindgren <tony@atomide.com>

As we have support for this in board-rx51-peripherals.c, let's
add it to the .dts files too.

Note that the reset GPIO will eventually go to the driver.
For now let's just pull it down and skip any further reset
in case the bootloader has configured the MAC address so
NFSroot works.

Also note that after 3430-sdp are using proper GPMC timings
we can remove the tests for smsc,lan91c94 in gpmc.c.

This is no longer needed as the device specific wake-up event
can now be specified with interrupts-extended property where
the second interrupt is the pinctrl-single register, such as
the UART3 RX pin.

Note that twl4030_omap3.dtsi needs to set WAKEUPENABLE for
off-idle to properly trigger the PMIC scripts. And GPIO pins
still need to set WAKEUPENABLE for wake-up events.

Compared to legacy booting, we don't have wake-up events enabled
for device tree based booting. This means that if deeper idle
states are enabled, the device won't wake up to UART events and
seems like it has hung.

Let's fix that by adding the wake-up interrupt. Note that we
don't need to set the PIN_OFF_WAKEUPENABLE any longer, that's
handled by the wake-up interrupt when the serial driver does
request_irq on it.

Tested with the following on omap3-overo-summit that has the
ES2.1 omap:

#!/bin/bash

uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
        echo 3000 > $uart/autosuspend_delay_ms

We've had deeper idle states working on omaps for few years now,
but only in the legacy mode. When booted with device tree, the
wake-up events did not have a chance to work until commit
3e6cee17 ("pinctrl: single: Add support for wake-up interrupts")
that recently got merged. In addition to that we also needed
commit 79d97015 ("of/irq: create interrupts-extended property")
that's now also merged.

Note that there's no longer need to specify the wake-up bit in
the pinctrl settings, the request_irq on the wake-up pin takes
care of that.

The RFBI node for OMAP DSS was left out when adding the rest of the DSS
nodes, because it was not clear how to set up the clocks for the RFBI.

However, it seems that if there is a HWMOD for a device, we also need a
DT node for it. Otherwise, at boot, we get:

WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/omap_hwmod.c:2542 _init+0x464/0x4e0()
omap_hwmod: dss_rfbi: doesn't have mpu register target base

required by the RFBI, let's add the RFBI node to get rid of the

  The delta is a largeish negative delta, due to revert of SMP support

  I didn't see a need for a full revert of the whole platform due to

   - some MTD/NAND fixes for OMAP
   - minor DT fixes for shmobile
   - warning fix for UP builds on vexpress/spc
