Patch P17 corruption bug on Samsung M8G2FA fwrev 0x11 eMMC parts

This firmware patch, for a bug of unknown impact, comes via the Nook
Color 1.4.3 kernel source:

As the patching method is very similar, we reuse the infrastructure for
patching the Samsung wear-leveling bug.  As with that bug, the patch is
stored in SRAM and is reapplied every time the chip is powered on.
