This is to simplify maintenance. It's easy to say now which patches need
some extra work and/or sending upstream. Updating to newer backports
should be also simpler with this.

Backport patches that separate spectral scan support from general debugfs
support of ath9k/ath10k; this allows to remove the dependency on
KERNEL_RELAY from these driver packages even with debugfs enabled and
avoids the memory footprint of the relay buffers allocated by ath9k/ath10k
even when they aren't used at all.
The KERNEL_RELAY dependency is moved to a new config symbol that enables
spectral scan support in these drivers.
