wifi: iwlwifi: prepare for reading SAR tables from UEFI

The driver will support reading BIOS tables from UEFI
too. Refactor the SAR tables (WRDS, EWRD, WGDS) flows:

1. Move all the SAR logic/definitions that is common to both
   UEFI and ACPI to a new file - regulatory.h/c.
2. Rename the relevant functions/definitions
   so it will be clear which is ACPI specific and which is
   for both ACPI and UEFI
3. Rename the function that copies the stored tables into the different
   commands structures, so will be clear what these functions do.
