ext4_utils: Yet another MMC discard pain in the ass

 * Secure discard on this device is painfully slow. Use regular
   discard until the issue is sorted out.

ext4_utils: add BoardConfig define to suppress EMMC-corrupting wipe command

If BOARD_SUPPRESS_EMMC_WIPE is true, the EMMC wipe command will not be
issued. This works around a bug in some firmware revisions of Samsung EMMC's
that permanently damages the device when the wipe command is issued.

For affected devices with kernel source, MMC_CAP_ERASE should be removed
from the kernel instead.

This is only part of the solution but it does handle the "flashing CM9
for the first time on an unsafe kernel" situation.
