TCPMv2: Add new override function for getting default Rp
This CL addes a new overridable function
typec_get_default_current_limit_rp() which is used in place of
CONFIG_USB_PD_PULLUP to retrieve the correct Rp value to reflect the
current limit. This functionality is required for boards which are not
per port symmetric.
Unless this function if overridden in a board/basebard specific file,
there is no change in functionality from present design.
BUG=b:191793195
BRANCH=quiche
TEST=verfied on Gingerbread that Rp = 3.0A is selected for C0 and Rp =
1.5A is selected for port C1.
