mmc: msm_sdcc: Add prog done interrupt support
Enable prog done interrupt for stop command(CMD12) that is sent after a multi-block write(CMD25). The PROG_DONE bit is set when the card has finished its programming and is ready for next data. After every write request the card will be polled for ready status using CMD13. For a multi-block write(CMD25) before sending CMD13, stop command (CMD12) will be sent. If we enable prog done interrupt for CMD12, then CMD13 polling can be avoided. The prog done interrupt means that the card is done with its programming and is ready for next request.
