mb/google/brya/var/nereid: Configure descriptor for either Type-C or HDMI

Some bytes in the descriptor need to be set differently for Type-C and
HDMI. To allow using a single firmware variant for both cases, update
the descriptor at runtime based on fw_config. This is a temporary
workaround while we find a better solution.

The byte values were determined by changing the following CSE strap and
comparing the generated descriptors:
Type-C: TypeCPort2Config = "No Thunderbolt"
HDMI:   TypeCPort2Config = "DP Fixed Connection"

BUG=b:226848617
TEST=Type-C and HDMI both work on nereid with fw_config set correctly.
