1949c0b52f hv: riscv: add get/set_pcpu_id and start_pcpus implementation
Use tp register to hold the current logical CPU ID. This follows the
same design as x86 which uses MSR_IA32_SYSENTER_CS for the same purpose.
riscv uses SBI HSM to start the APs.

41f04b4e7a HV: abstract percpu structure from x86 arch
Move x86 architecture dependent per cpu data into a
seperate structure and embeded it in per_cpu_region.
caller could access architecture dependent member by
using prefix 'arch.'.

v2->v3:
move whose_iwkey, profiling_info and tsc_suspend to x86
v1->v2:
rebased on latest repo

b8542f7def hv: riscv: per_cpu: add initial version
Since smpcall depends on the per_cpu_region data structure to access
smp_call_info_data, this patch adds the initial version of per_cpu
support on RISC-V. For now it only includes SMP call related info.

Further refinement will be done in the platform initialization patchset
(by Hang).
