wifi: rtw89: regd: judge UNII-4 according to BIOS and chip
For realtek regulatory, there are following two kinds of configurations
to determine whether to allow UNII-4 band, i.e. 5.9GHz channels.
1. default setting according to whether chip support it or not
2. evaluate realtek ACPI DSM with RTW89_ACPI_DSM_FUNC_59G_EN (func. 6)
If (1) is false, we won't try (2) and just disallow UNII-4. Otherwise,
if (2) is not supported or returns a non-specific value, we follow the
default setting either. Besides, this commit aims to add decision logic
in rtw89 regulatory. Actually, driver doesn't register UNII-4 yet. That
will be handled by another commit.
