Kodama: delay to enable charger EOC and TE function
When the battery is activated in shutdown mode, the battery needs
H/W Initialization and Cu Deposition Checking in 4.2 second.
Meanwhile, if the charger EOC function is enabled, charger will
close/open the charging path repeatedly and will pull PMIC's VSYSSNS
power.
It's a workaround to delay 4.5 second to enable charger EOC and TE
function.
BUG=b:148045048
TEST=The adapter can boot the DUT automatically when the battery
enters shutdown mode or ship mode.
