riscv: mm: Control p4d's folding by pgtable_l5_enabled

Browse source

To determine pgtable level at boot time, we can not use helper functions
in include/asm-generic/pgtable-nop4d.h and must implement these
functions. This patch uses pgtable_l5_enabled variable instead of
including pgtable-nop4d.h to controle p4d's folding, and implements
corresponding helper functions.
