rS360635: Set LG_VADDR to 48 on RISC-V.

Summary

The Sv48 PTE format is the largest currently defined address space for
RISC-V. It makes no sense to define a larger size and doing so (at
least for 64-bits) forces rtrees down a slow path.

There should likely be a corresponding change to the configure script upstream (probably duplicating the arm64 case).
