[PATCH rtw-next v2 08/12] wifi: rtw89: acpi: support loading GEO SAR tables

[Ping-Ke Shih <pkshih@realtek.com>]

From: Zong-Zhe Yang <kevin_yang@realtek.com>

Support to load GEO (geography) SAR tables with ACPI RWGS method. When
SAR values could be different by regulatory, GEO SAR can be used. The
format of GEO SAR is like the following, where regulatory number, band
number, and delta number are determined by header of either static SAR
or dynamic SAR. (It also means that no GEO SAR will be considered when
neither static SAR nor dynamic SAR is configured.)

                               delta number
                             /               \
                    + +-----+-----------------+
                  / | | max | delta...        | \
                 /  | +-----+-----------------+  band
                /   | | max | delta...        |  number
               /    | +-----+-----------------+
              /     | |...                    | /
                    + +-----+-----------------+
                    | | max | delta...        | \
       regulatory   | +-----+-----------------+  band
       number       | | max | delta...        |  number
                    | +-----+-----------------+
                    | |...                    | /
                    + +-----+-----------------+
              \     | |...                    |
               \    | |...                    |
                \   | |...                    |
                 \  | |                       |
                  \ | |                       |
                    + +-----+-----------------+

Each entry of GEO SAR contains delta field(s), which are offset(s) used
to tweak the loaded static/dynamic SAR table(s) by antenna, and one max
field, which describes the maximum of the final SAR values after tweaked.
Different entries should be configured based on both regulatory and band.
