XXX add address to CMD_STATUSlr/nand/cafe-nand-exec-op-debug
cafe_nand_cmdfunc() would previously do:
/* And one address cycle -- even for STATUS, since the controller doesn't work without */
adrbytes = 1;
Without it, I'm reading status of 0xc1 (that's FAIL | READY | WP), which is
probably garbage.
