With NO_BOOTMEM change, now we use memblock allocator to reserve space for crash kernel to have one less dependency with nobootmem allocator wrapper. Tested with both flat memory and sparse (faked) memory models with highmem enabled.

A new ARCH_SHMOBILE_MULTI configuration symbol has been created to group all multiplatform-enabled SH-Mobile SoCs. The existing ARCH_SHMOBILE configuration symbol groups SoCs that haven't been converted yet. This arrangement works fine for the arch/ code, but lots of drivers needed on both ARCH_SHMOBILE and ARCH_SHMOBILE_MULTI depend on ARCH_SHMOBILE only. In order to avoid changing them, rename ARCH_SHMOBILE to ARCH_SHMOBILE_LEGACY, and create a new boolean ARCH_SHMOBILE configuration symbol that is selected by both ARCH_SHMOBILE_LEGACY and ARCH_SHMOBILE_MULTI.

This can happen in practice on ARM where foreign pages can be above 4GB even though the local kernel does not have LPAE page tables enabled (which is totally reasonable if the guest does not itself have >4GB of RAM). In this case the kernel still maps the foreign pages at a phys addr below 4G (as it must) but the resulting DMA address (returned by the grant map operation) is much higher. This is analogous to a hardware device which has its view of RAM mapped up high for some reason. This patch makes I/O to foreign pages (specifically blkif) work on 32-bit ARM systems with more than 4GB of RAM.
