n7000: Set BOARD_SUPPRESS_EMMC_WIPE
Nearly all N7000 units have a defective Samsung eMMC chip
(VYL00M fwrev 0x19) that cannot handle MMC ERASE commands.
This is the cause of rampant bricking of devices seen on XDA,
especially since the shipment of official ICS releases like
XXLPY.
While our kernel currently blocks ERASE commands making this
redundant, it's best to be doubly safe. Also, this should
disable ERASE functionality in our updater-scripts, rendering
them safe to flash even on "dangerous" kernels. (This needs
testing to be sure.)
