Merge tag 'cleanup' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull first batch of arm-soc cleanups from Olof Johansson:
"These cleanups are basically all over the place. The idea is to
collect changes with minimal impact but large number of changes so we
can avoid them from distracting in the diffstat in the other series.
A significant number of lines get removed here, in particular because
the ixp2000 and ixp23xx platforms get removed. These have never been
extremely popular and have fallen into disuse over time with no active
maintainer taking care of them. The u5500 soc never made it into a
product, so we are removing it from the ux500 platform.
Many good cleanups also went into the at91 and omap platforms, as has
been the case for a number of releases."
Trivial modify-delete conflicts in arch/arm/mach-{ixp2000,ixp23xx}
