[PATCH] riscv: Use p*d_leaf macros to define p*d_huge

[Alexandre Ghiti]

The newly introduced p*d_leaf macros allow to check if an entry of the
page table map to a physical page instead of the next level. To avoid
duplication of code, use those macros to determine if a page table entry
points to a hugepage.
