gingerbread: Account for port C1 1.5A current limit
This CL adds an override function for
typec_get_default_current_limit_rp() for gingerbread. This allows port
C0 to have a 3.0A current limit as desired, and still limit C1 to
1.5A.
A new macro BOARD_C1_1A5_LIMIT was added to allow this feature to be
used for honeybuns variants. This macro is also used to adjust the
USB-PD SRC CAP current limit to 1.5A
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.
