Merge branch 'mxc-master' of git://git.pengutronix.de/git/imx/linux-2.6 into imx/master

Removed selection of COMMON_CLKDEV by CONFIG_ARCH_MX5.  This is handled
in 03e09cd8902717b66f940357257d8ad76114d9f2.

arch/arm/plat-mxc/iomux-mx1-mx2.c was moved to
arch/arm/plat-mxc/iomux-v1.c in 5e2e95f520538e095d10456acd28d9107317aa32
and got bug fixed in 5c17ef878fa25e04b1e8f1d8f5fa8b267753472c.  The bug
in arch/arm/plat-mxc/iomux-v1.c isn't present any more since
bac3fcfad565c9bbceeed8b607f140c29df97355, so
arch/arm/plat-mxc/iomux-mx1-mx2.c is simply deleted.

Conflicts:
