Sparsemem is used to store page structs and other information for each physical page in the system. In order to support 52-bit physical memory, increase MAX_PHYSMEM_BITS to 52 when 52-bit physical memory is configured. If it is not configured, then the kernel can't use 52-bit memory, so leave MAX_PHYSMEM_BITS at 48 in that case. (The kconfig option to set ARM64_PA_BITS to 52 will be added in a later patch.)
