target/arm: Implement Neoverse N2 CPU model
Implement a model of the Neoverse N2 CPU. This is an Armv9.0-A
processor very similar to the Cortex-A710. The differences are:
* no FEAT_EVT
* FEAT_DGH (data gathering hint)
* FEAT_NV (not yet implemented in QEMU)
* Statistical Profiling Extension (not implemented in QEMU)
* 48 bit physical address range, not 40
* CTR_EL0.DIC = 1 (no explicit icache cleaning needed)
* PMCR_EL0.N = 6 (always 6 PMU counters, not 20)
Because it has 48-bit physical address support, we can use
this CPU in the sbsa-ref board as well as the virt board.
