MMU registers were exposed to user-space using sregs interface. Add them
to ONE_REG interface and use kvmppc_get_one_reg/kvmppc_set_one_reg delegation

- Restrict set_one_reg operation for MMU registers to HW values
Documentat
Enable basic support for Freescale e6500 core, adding MAV 2.0 support.
Validated on T4240QDS platfrom. Altivec, Multithreading and HW Tablewalk
are not addressed by this patchset.

Vcpu's MMU default configuration and geometry update logic was buried in
a chunk of code. Move them to dedicated functions to add more clarity.
