When the system is compiled without CONFIG_DMI, the function
here statically returns NULL, leading to a compiler warning.
Catch that and print "<unknown>" in that case.
While at it, fix some indentation in the function.

Try to read the ECKV table from UEFI first,
and if the WIFI UEFI tables are unlocked or the
table doesn't exist - try to read it from ACPI.
Change iwl_acpi_get_eckv() to receive fwrt as argument so
it will be the same as all iwl_acpi_get_x() functions,
so it could be generated by the macro.
While at it - move the reading of ECKV to INIT stage. There is no
reason to read it each time we load the FW.

Currently the TAS 'read-from-BIOS' flow receives the command struct
and the version of it as read from FW TLVs, and fills the command
accordingly.
This seems wrong, we should have the 'read-from-BIOS' flow
(iwl_acpi_get_tas in iwlwifi) reading/parsing/validating the table from
BIOS, and the 'send-to-FW' flow (iwl_mvm_tas_init) doing
all the FW versioning checks and cmd filling.
Move the cmd filling to the 'send-to-fw' flow.

We are going to support reading BIOS tables from UEFI
too, Refactor the TAS table flow:
1. Rename and move the common code to the regulatory.h/c files.
2. Remove the IWL_TAS_BLOCK_LIST_MAX, as we can use IWL_WTAS_BLACK_LIST_MAX
instead.

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.

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.

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

3. Rename the function that copies the stored tables into the different
commands structures, so will be clear what these functions do.
