ARM: 8025/1: Get rid of meminfo memblock is now fully integrated into the kernel and is the prefered method for tracking memory. Rather than reinvent the wheel with meminfo, migrate to using memblock directly instead of meminfo as an intermediate.

ARM: Add arm_memblock_steal() to allocate memory away from the kernel Several platforms are now using the memblock_alloc+memblock_free+ memblock_remove trick to obtain memory which won't be mapped in the kernel's page tables. Most platforms do this (correctly) in the ->reserve callback. However, OMAP has started to call these functions outside of this callback, and this is extremely unsafe - memory will not be unmapped, and could well be given out after memblock is no longer responsible for its management. So, provide arm_memblock_steal() to perform this function, and ensure that it panic()s if it is used inappropriately. Convert everyone over, including OMAP. As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot with this change. Mark this option as BROKEN and make it depend on BROKEN. OMAP needs to be fixed, or 137d105d50 (ARM: OMAP4: Fix errata i688 with MPU interconnect barriers.) reverted until such time it can be fixed correctly.
