Each ACPI table has its own version number. Add the version numbers in a single function so we can keep them consistent and easily see what versions are supported.
Start a new acpi_table file in a generic directory to house this function. We can move things over to this file from x86 as needed.

Is it for real this fancy numbering? I don't remember spec by heart, perhaps this needs to be elaborated in the comment.

This should be cleaned according to uefi.org, i.e. not all above tables are from ACPI spec. And thus, should be rather in the below section.
- /* Additional proprietary tables */
- ACPITAB_VFCT,
- ACPITAB_NHLT,
- ACPITAB_SPMI,
Where is SPCR?
- ACPITAB_COUNT,
