Shiqing Gao 4544d28ee1 hv: fix 'User name starts with underscore'
There are chances that names with leading underscore declared by
developers are conflict with the ones reserved for the compiler.

What this patch does:
- rename these functions/variables/macros starting with
  underscore to avoid such unintentational mistakes.
- remove gpr.h without any contents

Binbin Wu b2802f3d1d hv: cpu: align general-purpose register layout with vmx
In current code, general-purpose register layout in run_context is not align with the
general-purpose register index when vmexit. So hv needs to map the index used during
vmexit to the index of the general-purpose register in run_context.
This patch align the layout, so that no mapping needed.

Xiangyang Wu 2a2adc76f6 HV:CPU:Fix a mistake introduced by MARCO replacing patch
Fixs: 7fd3c624 (HV:CPU:Constant values replace with
CPU MACRO)
There is a mistake in the previous MARCO replacing patch,
use CR4 value replaces CR0 MACRO.

Use CR0 value replaces CR0 MACRO.

Xiangyang Wu 0f6ff87835 HV:CPU:Constant values replace with CPU MACRO
MISRA C requires that all unsigned constants should have
the suffix 'U/UL'(e.g. 0xffU), but the assembler may not
accept such C-style constants.

To work this around, all  unsigned constants must be
explicitly spells out in assembly with a comment tracking
the original expression from which the magic number is
calculated.

Yin Fengwei 02d819144e hv: add enter_s3
enter_s3 is main function for ACRN to enter S3 state with following
process:
 - pause vm0
 - save the wakeup vec of vm0 and set wakeup vec of ACRN. So
   resume from S3 will jump to ACRN wakeup
 - offline APs
 - update the main entry of trampoline to resume entry. After BSP
   is resume from S3, it will jump to resume entry instead of AP
   startup routine
 - turn off vmx
 - suspend devices
 - enter S3.

exit S3 with following process:
 - release trampoline_spinlock which is hold in trampoline code
 - resume devices
 - enable vmx
 - update the main entry of trampoline to AP startup routine.
 - online APs.

The following operations will be resume vm0 which will be added
in next patch.
