This patch series is based on a previous patch series which adds the framework
to allow enabling writable from userspace for CPU ID register easily. That patch
series is at https://lore.kernel.org/all/20230317050637.766317-1-jingzhangos@google.com.

This patch series shows how easy to enable writable for feature fields with
dependencies and enable writable for a bunch of feature fields in an ID register.
