Driver: isl9237: configures ACOK assertion to switching time
Isl9237 default setting sets 1.3s debounce time from ACOK assertion
to switching. It's too long for EC being notified AC is present.
Change the value to 150ms.
BUG=none
BRANCH=glados
TEST=In Kunimitsu system, plug in Zinger and capture timestamp when EC
receive AC_PRESENT interrupt, it's reduced by ~1.2s.
