Blackfin: don't support keypad wakeup from hibernate
The on-chip keypad peripheral requires different registers to be setup depending on the standby type (standby vs hibernation). However, since the power management framework doesn't differentiate between these types, the driver doesn't know which registers to program and subsequently it avoids doing so. Always enabling the keyboard wakeup source causes misbehavior when the pins are not assigned to the keypad. If they happen to drive a certain level, they'll trigger a wake up event which is not wanted. So until the aforementioned issue can be sorted out, drop support for the wakeup source completely.
