arch/arm64/armv8/mmu: Add support for 48bit VA

The VA space needs to be extended to support 48bit, as on Cavium SoCs
the MMIO starts at 1 << 47.

The following changes were done:
* Add a Kconfig to define the VA space on platform level and support
  64KB granular size for VA > 39.
* Decide to use either 4KB granule or 64KB granule depending on
  supported VA space.
* Add helper functions for different page level sizes
* Add asserts to make sure that the address is withing the VA
* Don't use BLOCK in level1 if not on 4KB granule

Tested on Cavium SoC.
Needs tests on other platforms.
