Revert "gpio: omap: Fix lost edge wake-up interrupts"
This reverts commit a522f1d0c381c42f3ace13b8bbeeccabdd6d2e5c. 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.
