Subject: [RFC PATCH 03/17] fsl_rio: Remove FreeScale e500 conditionals

The "CONFIG_E500" conditional should be unnecessary.  The fsl_rio
hardware is only present on MPC85xx (e500/e500mc) anyways, although it
should build everywhere for better compile-test coverage.

The conditionally-defined fsl_rio_mcheck_exception() function lost its
two e500-specific constants in commit 82a9a4809f:
  powerpc/e500: fix breakage with fsl_rio_mcheck_exception

Specifically, the references to SPRN_MCSR and MCSR_BUS_RBERR were moved
to an e500-specific file.

This patch just removes the unnecessary #ifdef, as the entire file is
effectively dead code on non-e500 platforms anyways.
