Pins that have MFP_LPM_KEEP_OUTPUT set and are configured for output
must retain the output state in low power mode.
Currently, the pin direction configuration is overrided with values
in gpdr_lpm[] array and do not obey the MFP_LPM_KEEP_OUTPUT setting.
Fix the above bug and add some documentation to clarify the
MFP_LPM_KEEP_OUTPUT setting purpose.

Some pins are expected to keep their last level during suspend, and
introduce MFP_LPM_KEEP_OUTPUT for this.

This just leaves include/asm-arm/plat-* to deal with.
