Sainath Grandhi 5a51d0bfb5 hv: Add host CR2 to exception dump
ACRN dumps host registers in case of an exception in root mode operation.
This patch adds CR2 register to the dump. It is useful for

Sainath Grandhi e91d7402d5 hv: Debug messages from a CPU are overlapped with other CPUs messages
In the cases when more than one CPU has something to print, exception
dump from one CPU is overlapped with other CPU's messages and the final
text that is printed on console is all mixed up and does not make any sense.
Changing printf to pr_err so that the messages are printed one after
the other.

Jason Chen CJ 2d469a5e5f modularization: hypervisor initilization component
hypervisor initilization component triggered by boot component,
and it calls different components initilization functions from
the highest layer.

this patch added init.c and move reorged cpu init functions into
it, keep hardware management functions in cpu.c but move other
components' init function into init.c.

the hypervisor initilization components will call:
- init_cpu_pre
- init_cpu_post
- init_bsp
- init_debug_pre
- init_debug_post
- init_guest
- init_passthru
- enter_guest_mode

the hypervisor initilization component include files:
arch/x86/init.c
include/arch/x86/init.h

this component is higest layer, so there is no reverse dependencies for it.

v2:
- separate into 2 patches, 1 for reorg, 1 for pure move.

Jason Chen CJ 3d5d6c96ec vcpu: add get/set register APIs

- runtime contexts always saved/restored during VM exit/entry, which
  include general registers rax/rcx/rdx/rbx/rbp/rsi/rdi/r8~r15, cr2 and
  msr for spectre control (ia32_spec_ctrl)
- runtime contexts on-demand cached/updated during VM exit/entry, which
  include frequently used registers rsp, rip, efer, rflags, cr0 and cr4
- runtime contexts always read/write from/to VMCS, which include left
  registers not in above

this patch add get/set register APIs for vcpu runtime contexts, and unified
the save/restore method for them according to above description.

v3:
- update vcpu_get/set_cr0/4 as unified interface to get/set guest cr0/cr4,
  use on-demand cache for reading, but always write to VMCS for writing.
