According to the comments in hypervisor:
" This file includes config header file "bsp_cfg.h" and other
hypervisor used header files.
It should be included in all the source files."
this patch includes all common header files in hypervisor.h
then removes other redundant inclusions

The cx data is hardcoded within HV, load it to boot_cpu_data when HV boot.
The patch provide a3960 soc cx data for example.

Split pm.c from cpu_state_tbl.c to put guest power management related
functions, keep cpu_state_tbl.c to store host cpu state table and
related functions.

Currently acrn partitions cpus between SOS and UOS, so the default
policy is to allow guest managing CPU px state. However we would
not blindly passthrough perf_ctrl MSR to guest. Instead guest access
is always trapped and validated by acrn hypervisor before forwarding
to pcpu. Doing so leaves room for future power budget control in
hypervisor, e.g. limiting turbo percentage that a cpu can enter.

The vm px info would be used for guest Pstate control.
Currently it is copied from host boot cpu.

The patch takes Intel ATOM A3960 as example that hard code all Px info
which is needed for Px control into Acrn HV and load it in boot process.
