a68f655a11 HV: update ept address range for pre-launched VM
For a pre-launched VM, a region from PTDEV_HI_MMIO_START is used to store
64bit vBARs of PT devices which address is high than 4G. The region should
be located after all user memory space and be coverd by guest EPT address.

This patch does the following,
1. Removes RDT code if CONFIG_RDT_ENABLED flag is
not set.
2. Set the CONFIG_RDT_ENABLED flag only on platforms
that support RDT so that build scripts will automatically

b8a021d658 HV: split L2 and L3 cache resource MSR
Upcoming intel platforms can support both L2 and L3

So split the MSRs so that we can support allocation

2. Replace generic platform_clos_array struct with resource

5398c901f6 hv: remove CONFIG_PARTITION_MODE for pre-launched VM vE820 creation
Preparing for hybrid mode:

- create vE820 for pre-launched VMs and do other init code when the
  vm_config->type is PRE_LAUNCHED_VM.
- create ve820.c for each board because without wrapping by
  CONFIG_PARTITION_MODE, ve820_entry[] needs to be visible even when
  compiling target boards that haven't enabled pre-launched VMs.
- remove create_prelaunched_vm_e820() from vm.c and implement board
  specific function for each $(CONFIG_BOARD)/ve820.c. The reasons being:
  - don't need to define ve820_entry[32] for those boards that don't
    support pre-launched VMs.
  - more importantly, this makes it much easier to create different per-VM
    vE820 when it's needed.

649406b049 HV: refine location of platform_acpi_info header
platform_acpi_info.h should be BOARD specific so move the header file
to configs/$(CONFIG_BOARD)/ folder.

So the target acpi info file detect process is:

Compiler search for $(CONFIG_BOARD)_acpi_info.h under
hypervisor/arch/x86/$(CONFIG_BOARD)/ first (the file is supposed to be
generated by offline tool so it is not included in original source), if
found, then the file is the target acpi info file. If not and at the
same time the ENFORCE_VALIDATED_ACPI_INFO Kconfig was set, the compiler
will stop and hint user to add target acpi info file by offline tool.
If ENFORCE_VALIDATED_ACPI_INFO was unset, then compiler will continue to
search for platform_acpi_info.h as target acpi info file under
hypervisor/arch/x86/$(CONFIG_BOARD) folder (with this file we could bypass
ENFORCE_VALIDATED_ACPI_INFO check and benifit for development). If this
file is not exist, then hypervisor/arch/x86/configs/platform_acpi_info.h
will be included as final target acpi info.

The process should work for UEFI path also, with a valid platform acpi
info file, S3/S5 should work on UEFI platform.

c20d095a63 HV: refine sos_vm config header
The sos_vm config under arch/x86/configs/$(CONFIG_BOARD) folder should be
customer specific configuration, leave it back to customer.

When hypervisor start building, it will check whether BOARD specific sos_vm.h
exist in configs/$(CONFIG_BOARD) folder. If exist, then include this header;
if not, then include default sos_vm config header under configs/default folder.
