mb/google/poppy/variant/nocturne: increase touch panel power-on delay
The WACOM 5C01 touch panel power-up delay of 10mS is too aggressive
and causes "failed to change power setting" errors in the kernel, so
this change increases the power-up delay to 20mS which allows enough
time for the WACOM device's i2c controller to wake up.
BUG=b:120090384
BRANCH=none
TEST=flash and boot nocturne, log into kernel, execute the following
command and make sure the string is not found :
dmesg | grep "failed to change power setting"
