acpi: Add a central location for table version numbers

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.
