Peter Maydell noticed some missing updates to cpu-feature-registers.rst,
while looking at these a number of other other omissions and some
maintainability problems were observed.  Several registers and many
bitfields have not been added.  

Following discussion with Catalin we remove the numbering of the
registers in the first patch so that when we add the registers we can
add them in a roughly sorted order, then fix up the missing
documentation before sorting the existing entries in the file.

This whole area should have much better tooling, rather than having to
update multiple places and manually cross check several different places
including rarely used documentation we should be marking up the sysreg
descriptions and then either generating the data or validating against
manually updated copies.  Manually updated copies seem like a good idea
for the ABI documentation since while it's more work that would force
review.  I did start on some sketches, it seemed like it might make
sense to tackle along with using the MRS but the libraries for that
seem not to be progressing at any great rate, I'll dig the sketches out.
