ocpc: Disable linear precharge at ocpc reset state
When linear precharge is enabled, it may affect
the charging behavior from the primary charger IC.
Therefore as a part of the reset process, we need
to disable linear precharge to make sure primary
charger can work normally.
BUG=b:191347747
BRANCH=dedede
TEST=make BOARD=storo pass, and test C0 port can charge normally.
