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" The default value before updating the descriptor is Type-C, but this was chosen arbitrarily. BUG=b:226848617 TEST=Type-C and HDMI both work on nereid with fw_config set correctly.
