mb/google/nissa/var/craask: Extend sd_hold for touchpad/touchscreen
Extend sd_hold to meet touchpad/touchscreen SPEC.
touchscreen:
tHD > 100 ns
touchpad:
900 ns > tHD > 300 ns
After applied the change, the tHD meets reqirement.
touchscreen:
35 ns --> 260 ns
touchpad:
43 ns --> 368 ns
BUG=b:271524470
TEST=build and measure the timing meet SPEC
