power: supply: axp20x_usb_power: use correct register for input current limit
On the axp803 and axp813 chips register 0x30 bits 0-1 is the default current limit that gets applied after the pmic detects a CDP or DCP port. The correct field to set is 0x35 bits 4-7. This field only has nine values (out of the 16 possible if it used all the bits), so introduce a field size variable to take that into account.
