Kodama: limit the max input current as 2A
The 45W type-c adapter can support 5V/3A and 9V/3A but can not meet DOE
efficiency for those power, so it only put 5V/2A and 9V/2A on the label.
So we limit the input current to 2A to keep same with the certification.
BUG=b:146464104
TEST=the max charger IARCR value is 2A.
