Subject: zaurus-updater: support flashing of Cacko's mainte_fix.bin

Only for 128M clamshell models.

This is necessary if you want to change rootfs size over 64 MB.
It is flashed in the first 256k of the nand and overwrites the first 64k of the
Parameter Area (AdjValue, BootFlag, Version, Clock).

Version is included so verchg is not necessary.
