ath9k, ath10k(-ct): move spectral scan support under a separate config symbol

Browse source 
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.

Subject: [PATCH 2/2] ath10k: move spectral scan support under a separate
config symbol
At the moment, spectral scan support, and with it RELAY, is always enabled
with ATH10K_DEBUGFS. Spectral scan support is currently the only user of
RELAY in ath10k, and it unconditionally reserves a relay channel.
Having debugfs support in ath10k is often useful even on very small
embedded routers, where we'd rather like to avoid the code size and RAM
usage of the relay support. While ath10k-based devices usually have more
resources than ath9k-based ones, it makes sense to keep the configuration
symmetric to ath9k, so the same base kernel without RELAY can be used for
both ath9k and ath10k hardware.
