skylake: increase retry count in power up
During power up, system will wait at most CHARGER_INITIALIZED_TRIES
delay to check if battery percentage or negociated charger power can
meet minimum requirement. In some cases, it takes longer time(observed
negotiated to min power took 2 seconds). So increase
CHARGER_INITIALIZED_TRIES from 10 to 40 to give total 4 seconds delay.
BUG=chrome-os-partner:48339
BRANCH=none
TEST=Verified in Kunimitsu system, negotiation to 5V@3A is done within
retry/delay.
