The init page tables installed in either cpu_primary.S or trampoline.S
are 1:1 mapping and won't be changed in the future.
The 'actual' hypervisor page table installed in enable_paging() is 1:1
mapping currently but it could be changed in the future. Both hva2hpa() and
hpa2hva() are implemented based on these page tables and can't be used
when the init page tables take effect.
This patch does the following cleanup:
- remove all hva2hpa()/hpa2hva() before calling enable_paging()
- get_hv_image_base() returns HVA, not HPA. So add hva2hpa() for all cases
that are called afte enable_paging().

Assert that PCI devices discovered while booting the hypervisor do not
have more table entries than allowed by the compile-time configuration
(CONFIG_MAX_MSIX_TABLE_NUM).
The case were `msix.table_count` > `CONFIG_MAX_MSIX_TABLE_NUM` is fatal
since the init function in the handler for MSI-X (vmsix_init) only looks
at `table_count` when populating the table. Since
`CONFIG_MAX_MSIX_TABLE_NUM` is the max size of the table array entry in
the pci_msix struct. This will cause the msix handler to write outside of
the table array.

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.
