mmc_spi: generate response for send status command
A "send status" command is added with the commit "mmc: checking status after commands with R1b response". But the status register returned from send status command of SPI protocol is different from that of MMC/SD protocol. We do a simple test and generate a response in stead of full bit-by-bit translation. Signed-off-by: Thomas Chou <thomas@wytron.com.tw>
