brcmfmac: use ISO3166 country code and 0 rev as fallback on brcmfmac43602 chips

This uses ISO3166 country code and 0 rev on brcmfmac43602 chips.
Without this patch 80 MHz width is not selected on 5 GHz channels.

Commit a21bf90e92 ("brcmfmac: use ISO3166 country code and 0 rev as
fallback on some devices") provides a way to specify chips for using the
fallback case.

Before commit 151a7c12c4 ("Revert "brcmfmac: use ISO3166 country code
and 0 rev as fallback"") brcmfmac43602 devices works correctly and for
this specific case 80 MHz width is selected.
