Remove model information, encoding/decoding and reduce bookkeeping.
This, besides removing a lot of code and cleaning up the code, also
enables these features on many more CPUs that were enumerated before.

Supported write flag for registers.
currently write is enabled only for PMC MSR.

Introduce:
cat /sys/kernel/debug/x86/cpu/*
for Intel and AMD processors to view / debug the state of each CPU.
By using this we can debug whole range of registers and other
cpu information for debugging purpose and monitor how things
are changing.
This can be useful for developers as well as for users.
