mb/google/poppy/variants/nami: Add delay to enable_gpio during Elan power on
During measurement of signals during Elan touchscreen power on, saw
that the enable_gpio delay was not sufficient as there is a +1.5 ms
delay during power on. Adding more delay to take this into account.
BUG=b:78311818
BRANCH=None
TEST=probe power on signals to ensure meet timing requirements
