charge_manager: add host cmd to get port count
The kernel is only able to know the number of USB PD port through
EC_CMD_USB_PD_PORTS, but the kernel needs also to be able to know
that there is a dedicated port. Add a host command that will
return the total number of charge port (USB PD + BJ).
BRANCH=None
BUG=chromium:841944
TEST=Called command from kernel driver and checked that the port count
was the expected value.
