In this patch series, we try to make more register fields writable like
ID_AA64PFR1_EL1.BT since this can benifit the migration between some of the
machines which have different BT values.

Changelog:
----------
RFCv1 -> v1:
  * Fix the compilation error.
  * Delete the machine specific information and make the description more
    generable.

RFCv1: https://lore.kernel.org/all/20240612023553.127813-1-shahuang@redhat.com/
