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.
