Bug description:
  This patch could fix this issue, otherwise booting will take very long
  time.

  
  4e93b9a6abc0d028daf3c8a00cb77b679d8a4df4
  mmc: card: Don't access RPMB partitions for normal read/write
  During kernel boot, it will try to read some logical sectors
  of each block device node for the possible partition table.

  But since RPMB partition is special and can not be accessed
  by normal eMMC read / write CMDs, it will cause below error
  messages during kernel boot:
  ...
   mmc0: Got data interrupt 0x00000002 even though no data operation was in progress.
   mmcblk0rpmb: error -110 transferring data, sector 0, nr 32, cmd response 0x900, card status 0xb00
