ARM: ux500: delete U5500 support
This platform has been obsoleted and was only available inside of ST-Ericsson, no users of this code are left in the world. This deletes the core U5500 support entirely in the same manner as the obsoleted U8500 silicon was previously deleted. The cpu_is_u5500() macros that can read out the CPU ID is left until the next kernel cycle, this makes it possible to merge deletion of dependent drivers without breakage. This also has the upside of removing the mailbox driver which was our only driver that was outside the drivers/* hiearchy, now the machine directory only handles machines and nothing else.
