ISL9241: Change register settings for OCP
ISL9241: Change register settings for OCP

Register setting on the ISL9241 were causing overcurrent protection
(OCP) to be triggered.

ACILIM2 doesn't seem to be working properly, causing current spikes. 2
level current limiting isn't necessary so is disabled.

This was likely not seen on other platforms because SYV682 current limit
is much more sensitive to spikes than other Type-C PPCs.
