HV:Added support to perform MSR operation on all cpus

Browse Source 
MSR operations are directly done based on physical cpu's

profiling_handle_msrops:
	Per cpu function, performs the MSR operations (Read, Read clear,Write)
	For SOCWATCH/ power tool, generates MSR samples.

profiling_msr_ops_all_cpus :
	Receives required information for MSR operations from guest,
	SMP calls profiling_handle_msrops,
	Copies the information collected to guest
