Fizz: Limit input current
Fizz has an over current control system. There are two FETs
connected to two registers: PR257 & PR258. They control
the max input current as follows:
PR257, PR258
For 4.62A (90W BJ adapter), on, off
For 3.33A (65W BJ adapter), off, on
For 3.00A (Type-C adapter), off, off
BJ adapters are distinguished by reading GPIO71.
This patch also removes ISL9238 driver and ramping code. The
charger chip has been removed from the board since proto2.
BUG=b:65013352
BRANCH=none
TEST=Boot Fizz Proto3 on BJ and Type-C.
