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.

Can you please address Marc's feedback?

If we only make things writable a field at a time it's going to take
forever to catch up w/ the architecture.

Ok. I will update the patch series again with tackling the full register.

Thanks,
Shaoqin
