Add binary dump from yarvik tab26x stock firmware

This is a dump from the yarvik tab26x livesuit image. It contains the
android 4.0.3 nanda partition and some extra's that where extracted.

This is what is shipped on the device. Yes,
yarvik_tab26x/stock-nanda/linux/linux.bmp is broken and probably not on
purpose, just missed by accident.
Updated to android 4.0.4

This was an official vendor update to android 4.0.4. Some interesting
changes are the addition of several more bitmaps, fixing 'bugs' in
script.fex (sata_used = 0, which makes sense as the tablet does not
have any sata hardware connected). And cleanup of build.prop; They
removed the iNet 97F references and branded it as their own. Also
for some reason it was decided to swap Vol+ and Vol- keys. Highly
annoying.
