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 to coreboot and libpayload:
* Use page table lvl 0
* Increase VA bits to 48
* Enable 256TB in MMU controller
* Add additional asserts
Tested on Cavium SoC and two ARM64 Chromebooks.
