dedede/raa489000: Set LPM exit debounce to 100ms
For some reason, when the RAA489000 TCPC exits low power mode, CC
status doesn't appear changed when using a servo v4. This causes us
to think no connection is present and immediately but the IC back into
low power mode. If we wait 100ms before querying the CC status reg,
it seems that then the right values are reported.
This commit adds a workaround by setting the LPM exit debounce time to
100ms.
BUG=b:182429150,b:181308089
BRANCH=dedede
TEST=Build and flash a board, verify that servo v4 with an external
charger is detected.
