The function is called in a fully initialised C environment and calls
into other C functions. The Aarch differences are minimal and are hidden
by the pre-existing headers. Converting it results into cleaner code
that is the same across both Aarch64 and Aarch32.
To avoid having to do very ugly pointer arithmetic, define a C struct
for the cpu_ops for both Aarch64 and Aarch32.
