Here's a suggested commit message for merging early:

zork/var/ezkinil: Fix Touchscreen for schematic v3.6x

GPIO 90 (EN_PWR_TOUCHSCREEN) is set to PAD_GPO(GPIO_90, LOW), in
the trembyle baseboard code, but was overridden to PAD_NC(GPIO_90)
in the ezkinil-specific gpio configuration. This override causes
the touchscreen enable to fail. 
Removing the PAD_NC() override code fixes the issue.

This is urgently needed to get an official build for the reworked
board and to unblock the production of the next boards.  The
recently-introduced change that requires the fix is the new
schematic.

Obviously this fix is very limited in scope, affecting just the
ezkinil mainboard.
