Revert "gpio: omap: Fix lost edge wake-up interrupts"

Browse Source 
This reverts commit a522f1d0c3.

With cpu_pm handling fixed for omaps, and with gpio-omap now returning
notify error on pending interrupts, we can drop the old workaround for
seeing if there may be pending edge interrupts.

Depends-on: ARM: OMAP2+: Handle errors for cpu_pm
Depends-on: gpio: omap: Block idle on pending gpio interrupts
