mb/google/fatcat/var/francka: Reduce generic reset delay to 10ms

Browse source 
The existing 200ms `generic.reset_delay_ms` for the Francka variant
is unnecessarily long. This commit reduces the delay to 10ms.

A 10ms delay has been verified as adequate for the hardware to reset
correctly, maintaining touchscreen operation post-boot. This change
contributes to a slightly faster resume sequence (optimized by ~190ms)
by removing a superfluous wait time.

BUG=b:411164455
TEST=Able to boot google/francka with touchscreen functional.
