usb_prl_sm: reduce i2c transactions in FRS path
The get_cc function call is slow (2 i2c transactions in tcpci
implementation) and redundant in FRS path.
Use short-circuiting to remove the function call.
This saves ~2ms on Cherry.
BUG=b:190348051
TEST=Combined with other CLs in the chain, verify FRS workable on Tomato
BRANCH=none
