2024-02-02wifi: iwlwifi: validate PPAG table when sent to FWMiri Korenblit
We used to check enablement/validity of the PPAG table while reading it from BIOS. For newer FWs this checks were offloaded, and the driver needs to send the PPAG table anyway. The desicion whether the table needs to be validated before sending it is FW related and shouln't be in 'read-from-bios' flow. Move it to 'send-to-fw' flow instead. This will also help to avoid code duplication of checking validity in both ACPI and UEFI caes.

2024-02-02wifi: iwlwifi: prepare for reading PPAG table from UEFIMiri Korenblit
As PPAG table is going to be read from UEFI, there are some cleanups required: Move functions/definitions that are common to both UEFI and ACPI to regulatory.h/c. In addition, rename the functions/macros names so it will be clear which one is ACPI specific, and which is common for ACPI and UEFI.

All the regulatory tables will be read from UEFI, and only if it doesn't exist - they will be read from ACPI. Read SAR tables (WRDS, EWRD and WGDS) from UEFI.

2024-02-02wifi: iwlwifi: prepare for reading SAR tables from UEFIMiri Korenblit
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.
