HV: setup px info when create vm The vm px info would be used for guest Pstate control. Currently it is copied from host boot cpu. Signed-off-by: Victor Sun <victor.sun@intel.com> Acked-by: Kevin Tian <kevin.tian@intel.com>

int vm_load_pm_s_state(struct vm *vm);
HV:fixed "Pointer param should be declared pointer to const" Pointer param should be declared pointer to const if the parameter is keeped read-only. This patch changes pointer param whose name is vm.

int validate_pstate(const struct vm *vm, uint64_t perf_ctl);
hv: trap vm0 write/read pm1a/pm1b registers ACRN needs to trap the pm1a/pm1b written/read from VM0. So we could know when should we put the system to S3. We will have two path back to VM0: - S3 enter/exit sucess. Will reset VM0 and jump to VM0 wakeup vec with real mode - S3 enter/exit failed. Will return to the next instruction of pm1a/pm1b register writing. VM0 will read the pm1a/pm1b evt register to check whether it's waked up or not.
