UDOO board has a possibility to disable most of imx6 SoC power supplies via
"EN_5V" signal, which is connected to "NANDF_D4" pad.

This reduces current consumption after shutdown from ~350 mA to ~40 mA and
prevents a SoC watchdog from starting it again on its own after the
watchdog timeout expires (previously it was not possible to shut down the
SoC permanently if its watchdog was ever enabled since it was still ticking
after the shutdown).

Unfortunately, this does not extinguish the "Power" LED (as it is powered
from an always-on voltage regulator).

To power the SoC up again press the power button (SW2, the one with a long
shaft).

commit 200a575b ("ARM: dts: meson: organize devices in their corresponding busses")
organized all peripherals in busses so that the base register offset of
the bus doesn't have to be included in all child-nodes anymore.
The GPIO interrupt controller however specifies the register offset
without subtracting the "cbus" base address. This leads to a problem
where of_iomap inside the irq-meson-gpio driver fails because it
actually tries to map 0x182209880 (cbus base = 0xc1100000 + 0xc1109880
for the GPIO interrupt controller). Fix this by using 0x9880 as register
offset.
