On error syscon_regmap_lookup_by_phandle() returns ERR_PTR() value,
which makes a check for NULL invalid and may lead to oops on error
path.

The SNVS power key driver has suspend/resume functions that
are accessed using SIMPLE_DEV_PM_OPS, which hide the reference
when CONFIG_PM_SLEEP is not set, resulting in a warning about
unused functions:
drivers/input/keyboard/snvs_pwrkey.c:183:12: error: 'imx_snvs_pwrkey_suspend' defined but not used [-Werror=unused-function]
drivers/input/keyboard/snvs_pwrkey.c:194:12: error: 'imx_snvs_pwrkey_resume' defined but not used [-Werror=unused-function]
This adds __maybe_unused annotations to let the compiler know
it can silently drop the function definition.

Instead of inventing a new property name, let's use "wakeup-source" to
be consistent with other driver and subsystem bindings.

add snvs power key driver.
It work in imx chips after i.mx6sx
ON/OFF key used power on/off whole system.
This driver make it wakeup from suspend state when short press
ON/OFF key.
Long time press will trig SNVS power off chip without software
intervention.
