samus: Tweaks from bringup
- GPIO29 is no longer connected so we don't need the SMI workaround
on the entry to sleep states.
- Disable touchscreen wake source until the kernel driver is working
so it does not wake immediately.
- Update a few GPIOs and disable the codec for now as it is leaking
into the 1.8V DDR rail.
