mm: bring sparc pte_index() semantics inline with other platforms

pte_index() on platforms other than sparc return a numerical index.  On
sparc, it returns a pte_t*.  This presents an issue for
vm_insert_pages(), which relies on pte_index() to find the offset for a
pte within a pmd, for batched inserts.

This patch:
1. Modifies pte_index() for sparc to return a numerical index, like
   other platforms,
2. Defines pte_entry() for sparc which returns a pte_t*
   (as pte_index() used to),
3. Converts existing sparc callers for pte_index() to use pte_entry().

[[email protected]: remove pte_entry and just directly modified pte_offset_kernel instead]
