The Realtek Windows driver has defined these SAR tables for ages, and
people can install Linux on the x86 platform. To be consistent, implement
to apply these tables, and later Linux distro can also use the same rules.

The SAR tables include static SAR table for basic use, and dynamic SAR
table for platforms that can support yoga mode for example. GEO SAR
table is to support different country's regulations.

Since two antenna solution can possibly use different SAR limit, the last
three patches add this feature to chips that can support delta of TX power
from main antenna to aux antenna.

v2:
 - "wifi: rtw89: acpi: support loading dynamic SAR tables and indicator"
   (patch 7/12) is changed, because indicator field can be different
   for different CID.
