driver/intel/pmc_mux/conn: Move typec_orientation enum to coreboot_tables.h

Move the locally declared typec_orientation enum from chip.h to
coreboot_tables.h.

Change enum typec_orientation name to type_c_orientation for consistency
with contents of coreboot_tables.h.

Rename TYPEC_ORIENTATION_FOLLOW_CC to TYPEC_ORIENTATION_NONE.

BUG=b:149830546
TEST="emerge-volteer coreboot" and make sure it compiles successfully.
