This patch represents TSC freqeuency in KHz using a 32-bit unsigned integer.
The conversion macros between ticks and us/ms are changed to inline functions to
enforce the types of the input parameters. Note that us_to_ticks accepts only
uint32_t (~4K us at most) and never overflows.
Results of some unit tests on the conversion functions:
calibrate_tsc, tsc_khz=1881600
64us -> ticks: 120422
64us -> ticks -> us: 63
511us -> ticks: 961497
511us -> ticks -> us: 510
1280000 ticks -> us: 680
1280000 ticks -> us -> ticks: 1279488

Per MISRA C, operands to bit-wise operations should have unsigned
types. However, C99 prioritizes to use signed integers for hexadecimal constants
without the 'U' suffixes, leading to tons of bit operations on signed integers.
This patch series add the 'U' suffixes to the constants which are used in bit
operations, and add the intended width of these integers when applicable
(i.e. the target value is at least 32-bit wide) to avoid functional differences
due to signed vs. unsigned extensions. The rule of thumb is:
'0' for signed char/short/int
'0U' for unsigned char/short/int
'0L' for signed long (should be 64-bit)
'0UL' for unsigned long (should be 64-bit)

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

enable Xsave feature and pass-through it to guests
update based on v2:
- enable host xsave before expose it to guests.
- add validation for the value to be set to 'xcr0' before call xsetbv
when handling xsetbv vmexit.
- tested in SOS guest, created two threads to do different
FP calculations,test code runs in user land of sos.
