8852B, 8852C and upcoming 8851B can support U-NII-4, so add this patchset
to enable this feature. However, we can't turn it on unconditionally,
because hardware may not get certification in certain platforms, so add
a flag in BIOS ACPI to determine if we should disable these channels.

  wifi: rtw89: regd: judge UNII-4 according to BIOS and chip
