raa489000: Add raa489000_enable_asgate()
This commit exports a function to allow the ASGATE to be enabled or
disabled when the charger IC is in the READY state. This can help to
achieve a VBUS level of 0V if the READY state is required/desired.
BUG=b:183220414
BRANCH=dedede
TEST=With some other patches to use this function, build and flash on
madoo, plug in a charger, remove charger, verify that VBUS goes down
to less than 200mV and decays to 0.
