Remove redundant AH_DEBUG_ALQ.

[mips] [ar71xx] Since the wlan/ath drivers use ALQ, ensure we build the module
here otherwise we can't load said module.

[ar71xx] migrate all of the duplicate configuration out into a shared config file.

This brings the default configurations (drivers, net80211 settings, etc) and some

This should simplify building a lot of the same test images for my MIPS AP board
development and testing.

This is a work in progress; it's not designed to be perfect!
