qi-gta03-suspend-gpio.patch

Change to input / pulldown on most GPIO.  With no battery and just
USB power, this gets us into suspend with 9.5mA at 5V consumption... but
Ben Dooks told that we don't put the mDDR into deep sleep yet in the
platform pm code, so this should come right down when we have that.

The suspend is otherwise real though, PWREN to the PMU goes down, and
when we wake the device Qi is able to see it is a resume wake and jumps
back into Linux, where we currently die due to issues on s3c6410 platform
code getting worked on.
