drm/gma500: return errors from Oaktrail HDMI I2C reads
xfer_read() waits for the HDMI I2C transaction to reach
I2C_TRANSACTION_DONE, but it ignores both timeout and signal returns from
wait_for_completion_interruptible_timeout(). If the interrupt never
advances the transaction state, the loop can wait forever.
Return -ETIMEDOUT when the completion wait expires, propagate interrupted
waits, and make the I2C master_xfer callback return the first transfer
error instead of reporting a successful message count.
