Support for Non-zero HRMOR

Changes to kernel code to support detection and use of HRMOR
 offset in memory
Changes to tooling to handle the real memory offset
New interface to retrieve the physical address that
 corresponds to a virtual address

To test, run these commands before starting up Hostboot:
 system_cmp0.cpu0_0_05_0.write-reg HRMOR 0x8000000
 proc_venicechip_cmp0.phys_mem.del-map p8Proc0.l3_cache_ram 0 0
