wifi: ath12k: remove redundant regulatory rules intersection logic in host

Whenever there is a change in the country code settings from the
user, driver does an intersection of the regulatory rules for this
new country with the original regulatory rules which were reported
during initialization time.

There is also similar logic running in firmware with a difference
that the intersection in firmware is only done when the country code
is configuration during boot up time (BDF/OTP). Firmware logic does
not kick in when no country code is configured during device bring
up time as the device is always expected to have the country code
configured properly in the deployment.

There is a debug/test use case that requires absolute regulatory
rules to be used for a user configured country code when the device
is not configured with a particular country code during boot up time.

To support the above test use case, remove the redundant regulatory
rules intersection logic in the host driver. Depend on the
intersection logic in firmware when the device comes up with
pre-configured country code.
