[ar71xx] Outdoor 5GHz channels not available in Ubiquiti Bullet

Description

Hello,

rc1 for Barrier Breaker when installed on Ubiquiti Bullet M 5GHz device has disabled outdoor channels. Is it possible to change kernel settings to enable following two options for kmod-ath, please?

CONFIG_ATH_USER_REGD=y
CONFIG_PACKAGE_ATH_DFS=y

Currently, these are not set and in countries requiring DFS before the outdoor channels are activated, the latest versions are unusable.

Without CONFIG_PACKAGE_ATH_DFS set, only these channels are available:
