Running reboot command on the TQMa7 board would just hang infinite

Handling of i.MX7 errata e10574:
Watchdog: A watchdog timeout or software trigger will not reset the SOC.

Moved pinctrl from common mba7 to common tqma7 dtsi as it improves
readability of errata handling. Most integrators of this SoM will
likely use the development board as inspiration for handling this
SoC issue.

996MHz: VDDARM: 1.275V, VDDSOC: 1.175V;
792MHz: VDDARM: 1.150V, VDDSOC: 1.150V;
396MHz: VDDARM: 1.125V, VDDSOC: 1.150V;

Adding 25mV to cover board IR drop, for LDO enabled mode of 996MHz,
as the max value of LDO output can NOT exceed 1.3V, so 25mV is NOT

The LCD power sequencer is very finicky.  The backlight cannot
be driven until after the sequencer is done.  Until now, the
regulators were marked with 'regulator-always-on' to make sure
it came up before the backlight.  This patch allows the LCD
regulators to power down and prevent the backlight from being
used again until the sequencer is ready.  This reduces
standby power consumption by ~100mW.

The original submission had functional audio out and was based
on reviewing other boards using the same wm8962 codec. However,
the Logic PD board uses an analog microphone which was being
disabled for a digital mic.  This patch corrects that and
explicitly sets the gpio-cfg pins all to 0x0000 which allows the
analog microphone to capture audio.

The Kobo Aura is an e-book reader released in 2013.

With the devicetree in its current state, the kernel will boot and run
for about ten seconds. To solve this, the embedded controller needs to
be told that the system should stay powered on. This will be done in a
later patchset.

- The IOMUXC mode bits for the SD interfaces were taken from the
  vendor's U-Boot fork.
- The bus width of the eMMC is 4 bits in the vendor kernel, but I
  achieved better performance with 8 bits.
- The SDIO clock frequency for the WiFi chip is 25MHz in the vendor
  kernel, but the WiFi chip (BCM43362) supports 50MHz, which works
  reliably on this board and gives slightly better performance.
- The I2C pins' IOMUXC settings come from the vendor's U-Boot fork.

Note the GPIO polarity in the driver was ignored before and always
assumed to be active low, when all the DTs are fixed we will start
respecting the specified polarity. Switch polarity in DT to the
currently assumed one, this way when the driver changes the

Since 25aaa75d SDMA driver uses clock rates of "ipg" and "ahb"
clock to determine if it needs to configure the IP block as operating
at 1:1 or 1:2 clock ratio (ACR bit in SDMAARM_CONFIG). Specifying both
clocks as IMX5_CLK_SDMA results in driver incorrectly thinking that
