gpio/omap: handle save/restore context in GPIO driver
Modify omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle() functions
to handle save context & restore context respectively in the OMAP GPIO driver
itself instead of calling these functions from pm specific files.
For this, in gpio_prepare_for_idle(), call *_get_context_loss_count() and in
gpio_resume_after_idle() call it again. If the count is different, do restore
context.
