[lucid/fsl-imx51] UBUNTU: [Config] Disable parport_pc on fsl-imx51

BugLink: http://bugs.launchpad.net/bugs/601226

SRU Justification

Impact: when the parport_pc module is loaded, it triggers a panic (see
https://launchpadlibrarian.net/72913087/imx51-parport.txt)

Besides fixing this issue, also can't see any imx51 system which could
have a pc style parallel port.

I inserted a "Bump ABI" commit at the start of the series, plus I added 
some build glue 
(debian.fsl-imx51/abi/2.6.31-608.25/armel/ignore.modules) to your 
'UBUNTU: [Config] Disable parport_pc on fsl-imx51' patch.

git checkout -f fsl-imx51
git fetch origin && git fetch origin fsl-imx51
git reset --hard FETCH_HEAD
