bcm53xx: hack UBI to erase all dirty blocks left by CFE

UBI requires PEBs to be formatted (with a valid UBI header) or empty
(0xFF), however CFE doesn't clear blocks after flashing the image. To
workaround this problem, teach UBI to recognize EOF mark in a similar
way JFFS2 handles that in OpenWrt.
