drm/bridge: tc358767: Increase AUX transfer length limit
[ Upstream commit e0655feaec62d5139b6b13a7b1bbb1ab8f1c2d83 ]
According to the datasheet tc358767 can transfer up to 16 bytes via
its AUX channel, so the artificial limit of 8 appears to be too
low. However only up to 15-bytes seem to be actually supported and
trying to use 16-byte transfers results in transfers failing
sporadically (with bogus status in case of I2C transfers), so limit it
to 15.
