gpio: gpio-omap: Remove conditional pm_runtime handling for GPIO interrupts

Commit b764a5863fd8 ("gpio: omap: Remove custom PM calls and use cpu_pm
instead") moved interrupt using GPIO banks to idle with cpu_pm in order
to drop the use of pm_runtime_irq_safe() in a later patch. The GPIO
banks with no interrupts claimed are still being idled based on PM
runtime calls. However this caused a regression for am437x suspend for
rtc+ddr idle mode where the device cannot enter idle state as reported
by Keerthy <[email protected]>.

To fix the issue, we must not fail the pm_runtime callbacks. For GPIO
interrupts, we already have irq_chip_pm_get increment the PM runtime
use count as pointed out by Grygorii Strashko <[email protected]>.

So all we need to do is remove the conditional handling in the
runtime_suspend and resume functions and let the CPU PM notifier idle
the GPIO banks.
