ARC: mm: PAE40: Fix crash at munmap
commit 1c3c90930392 broke PAE40. Macro pfn_pte(pfn, prot) creates paddr
from pfn, but the page shift was getting truncated to 32 bits since we lost
the proper cast to 64 bits (for PAE400
Instead of reverting that commit, use a better helper which is 32/64 bits
safe just like ARM implementation.
