[PATCH v3 03/14] hexagon: remove __ARCH_USE_5LEVEL_HACK

The hexagon architecture has 2 level page tables and as such most of the
page table folding is already implemented in asm-generic/pgtable-nopmd.h.

Fixup the only place in arch/hexagon to unfold the p4d level and remove
__ARCH_USE_5LEVEL_HACK.
