Add a board specific helper to return USB PD port count
Certain SKUs of certain boards have less number of USB PD ports than
configured in CONFIG_USB_PD_PORT_MAX_COUNT. Hence define an overrideable
board specific helper to return the number of USB PD ports. This helps
to avoid initiating a PD firmware update in SKUs where there are less
number of USB PD ports. Also update charge manager to ensure that absent/
invalid PD ports are skipped during port initialization and management.
BUG=b:140816510, b:143196487
BRANCH=octopus
TEST=make -j buildall; Boot to ChromeOS in bobba(2A + 2C config) and
garg(2A + 1C + 1HDMI config).
