[PATCH 11/14] gpio: omap: Restore power_mode configuration at resume time

[Keerthy]

From: Dave Gerlach <d-gerlach@xxxxxx>

Commit 2dc983c565e0 ("gpio/omap: cleanup prepare_for_idle and
resume_after_idle") introduces omap2_gpio_prepare_for_idle and
omap2_gpio_resume_after_idle to properly configure gpios that are used
as wake sources. When entering off mode, omap2_gpio_prepare_for_idle
can set a flag indicating off-mode entry is desired, however once this
flag is set it is never cleared, so any additional calls to this
function, regardless of the mode, have this flag set.

This patch restores the pwr_mode flag to 0 in
omap2_gpio_resume_after_idle to ensure the flag is not misconfigured
during non off-mode operation.
