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" Change-Id: I1db0b3f5ce666b79d8ada2939ec865233ce52a56 Signed-off-by: Nick Vaccaro <nvaccaro@google.com> Reviewed-on: https://review.coreboot.org/c/29988 Reviewed-by: Duncan Laurie <dlaurie@chromium.org> Reviewed-by: Furquan Shaikh <furquan@google.com> Tested-by: build bot (Jenkins) <no-reply@coreboot.org>
