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
