apm821xx: wndr4700: interrupt-driven gpio-keys

Browse Source 
This patch fixes the active_low setting and
converts all of the physical keys on the wndr4700
to utilize the interrupt-driven gpio-keys driver
over the polled version.

The sdcard-insertion hack has been removed since the
block-subsystem will now be polling the device instead.
