It's hard for occasional GPIO code reader/writer to know if values 0/1
equal to IN or OUT. Use defined GPIO_LINE_DIRECTION_IN and
GPIO_LINE_DIRECTION_OUT to help them out.
NOTE - for gpio-amd-fch and gpio-bd9571mwv:
This commit also changes the return value for direction get to equal 1
for direction INPUT. Prior this commit these drivers might have
returned some other positive value but 1 for INPUT.

The GPIO controller doesn't have any controls to enable the system to
wake up from low power states based on activity on GPIO pins. An extra
hardware block that is part of the power management controller (PMC)
contains these controls. In order for the GPIO controller to be able
to cooperate with the PMC, obtain a reference to the PMC's IRQ domain
and make it a parent to the GPIO controller's IRQ domain. This way the
PMC gets an opportunity to program the additional registers required
to enable wakeup sources on suspend.

The new prefix allows the GPIOs to be uniquely identified on a per-chip
basis, which makes it easier to distinguish Tegra186 specific GPIOs from
those of later chips such as Tegra194 which supports a very different
set of GPIOs.

The IRQ core code refers to the interrupt type by that name, whereas the
term flow is almost never used. Some GPIO controllers use the term
flow_type, but it is most consistent to just go with the IRQ core
terminology.

Tegra186 has two GPIO controllers that are largely register compatible
between one another but are completely different from the controller
found on earlier generations.
