Merge branch 'ux500/delete-u5500' into next/soc 

Conflicts:
	arch/arm/mach-ux500/cache-l2x0.c
	arch/arm/mach-ux500/clock.c
	arch/arm/mach-ux500/cpu.c
	arch/arm/mach-ux500/mbox-db5500.c
	arch/arm/mach-ux500/platsmp.c
	arch/arm/mach-ux500/timer.c

Resolve lots of identical conflicts between the removal of
u5500 and the addition of u8540.
