From: Alessio Belle <alessio.belle@imgtec.com>
- Regenerate MMU defines to use GENMASK and BIT
- Use FIELD_PREP/GET to access page table entries and split virtual
addresses in their components
- Remove macros which can be reimplemented by FIELD_PREP/GET
- Remove other unnecessary macros
This should make the code a bit easier to maintain.
