ssi-sd now enters token mode as it returns the final R1 byte, so the
write-data token that immediately follows is not discarded. SPI CMD13
returns the internal sd_r1 response (upstream fix) instead of sd_r2_s,
which the adapter converts to the two-byte SPI R2 status; this stops the
repeated "Unexpected response to cmd 13" loop on guest status polls.
Drops the experimental store-TB TCI forcing and sd-watch OOB logging now
that the raw FAT32 image path is stable.
