The get_cpu_ops_ptr() function gets called from C (mainly in errata
reporting) but it is not PCS compliant - it clobbers r4 and r5. This
doesn't usually cause any problems, but if the stars align it blows up.
Convert the heart of the function to a non-PCS compliant macro that can
be invoked in the early entrypoint code and change the get_cpu_ops_ptr()
to a PCS compliant wrapper for calling into C. Additionally, the
resultant inlining in the entrypoint will lead to a tiny performance
bump due to the one fewer jump to an uncached memory location.
