TCPMv2: Preserve selected source current in FRS
When executing a fast role swap, ensure that any 3.0 A selected current
is preserved through the select_current_limit_rp in the TC layer.
Additionally, use this selected current to set our current limit when
first attaching as a source.
If FRS is disabled on a port, restore the default Rp value for the
board.
BRANCH=None
BUG=b:180434465
TEST=Check that a 3A FRS device loaded over 1.5 A is able to
successfully complete FRS
