Subject: sh: drop __pXd_offset() macros that duplicate pXd_index() ones

The __pXd_offset() macros are identical to the pXd_index() macros and
there is no point to keep both of them.  All architectures define and use
pXd_index() so let's keep only those to make mips consistent with the rest
of the kernel.
