atlas: run the TCPC I2C busses at 1MHz
this bumps up the I2C bus going to the TCPCs from 400KHz to 1MHz. we
do see improvement in the firmware update speed, but definitely not by
2.5x.
BUG=b:117525129
BRANCH=none
TEST=updated ps8751 firmware on atlas in combination with other
patches to enable TCPC firmware update
