casta: Configure number of PD ports basing on SKU ID
Bluebird board contains only one Type-C port. This patch
implements limiting number of available Type-C ports basing
on SKU ID.
Also obtaining SKU ID was implemented by fetching it from
EEPROM, similarly to garg board.
BUG=b:154602760
BRANCH=none
TEST=Flash on bluebird, open EC console.
Issue command 'typec 1 usb'.
Command should fail with information that
parameter 1 is invalid.
