ARM: initial multiplatform support
This lets us build a multiplatform kernel for experimental purposes. However, it will not be useful for any real work, because it relies on a number of useful things to be disabled for now: * SMP support must be turned off because of conflicting symbols. Marc Zyngier has proposed a solution by adding a new SOC operations structure to hold indirect function pointers for these, but that work is currently stalled * We turn on SPARSE_IRQ unconditionally, which is not supported on most platforms. Each of them is currently in a different state, but most are being worked on. * A common clock framework is in place since v3.4 but not yet being used. Work on this is on its way. * DEBUG_LL for early debugging is currently disabled. * THUMB2_KERNEL does not work with allyesconfig because the kernel gets too big [Rob Herring]: Rebased to not be dependent on the mass mach header rename. As a result, omap2plus, imx, mxs and ux500 are not converted. Highbank, picoxcell, mvebu, and socfpga are converted.
