riscv: mm: Define MAX_POSSIBLE_PHYSMEM_BITS for zsmalloc 



This definition is used by zsmalloc to optimize memory allocation. On
riscv64, it is the same as MAX_PHYSMEM_BITS from asm/sparsemem.h, but
that definition depends on CONFIG_SPARSEMEM. The correct definition is
already provided for riscv32.
