wifi: ath12k: update unsupported bandwidth flags in reg rules

The maximum bandwidth an interface can operate in is defined by the
configured country. However, currently, it is able to operate in
bandwidths greater than the allowed bandwidth. For example,
the Central African Republic (CF) supports a maximum bandwidth of 40 MHz
in both the 2 GHz and 5 GHz bands, but an interface is still able to
operate in bandwidths higher than 40 MHz. This issue arises because the
regulatory rules in the regd are not updated with these restrictions
received from firmware on the maximum bandwidth.

Hence, update the regulatory rules with unsupported bandwidth flags based
on the maximum bandwidth to ensure compliance with country-specific
regulations.
