Log Message:
Pull up following revision(s) (requested by jmcneill in ticket #67):
        sys/dev/sdmmc/ld_sdmmc.c: 1.28
        sys/dev/sdmmc/sdmmc_mem.c: 1.58-1.60
        sys/dev/sdmmc/sdmmcreg.h: 1.30, 1.31
        sys/dev/sdmmc/sdmmcvar.h: 1.25-1.27
Add discard support to ld@sdmmc using the ERASE (CMD38) command.
--
Read SD status register and print card status when a new SD card is found:
  sdmmc0: SD card status: 4-bit, C10, U1, V10
If the SD status register reports discard support, set the DISCARD arg to
the ERASE operation to let the card know that the host doesn't care if the
erase is performed.
--
Revert part of previous; the SD card spec recommends not to issue a DISCARD
command to the file system area.
