Revert "ath: add support for special 0x0 regulatory domain"

commit 1ec7ed5163c70a0d040150d2279f932c7e7c143f upstream.

This reverts commit 2dc016599c.

Users are reporting regressions in regulatory domain detection and
channel availability.

The problem this was trying to resolve was fixed in firmware anyway:

    QCA6174 hw3.0: sdio-4.4.1: add firmware.bin_WLAN.RMH.4.4.1-00042
