Consolitate writing bytes on the DAT lines by introducing
a pair of helpers to reuse in all commands receiving data.
I'm considering adding some 'process_completed_block' callbacks
to handle the different cases in sd_write_byte(), so this
function would become:
if (sd_generic_write_byte(sd, value)) {
sd->proto->process_completed_block[sd->current_cmd](sd);
}
But I ran out of time...
Full series for testing:
