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. The workaround_enabled flag is no more required and is removed.

"ctx" ?
Please change it to 'context' is subject and rest of the code.

Do you really need this wrapper. Use the funtion directly instead.
Rest looks fine to me
