Move most of CHANWIDTH_* definitions from ieee80211_defs.h to defs.h as
the definitions are getting used mostly for internal purpose only. Also
change prefix of the definitions to CONF_OPER_CHWIDTH_* and update in
all the files accordingly.
Leave the couple of VHT-specific exceptions to use the old defines (the
reason why they were originally added as VHT values), to avoid use of
clearly marked configuration values in information elements. In
addition, use the defines instead of magic values where appropriate.

This information element is similar to the CSA one. It contains a
counter and the target color. Once the counter expired, the change to
the new color happens.
Just note the current implementation is based on CCA counter attributes
that only take Beacon and Probe Response framesinto account.
(Re)Association Response frames do not currently have kernel APIs to
decrement the CCA counter since mediatek mcu firmware does not support
it yet and it will be added in future firmware release.

The HE Operation field for BSS color consists of a disabled, a partial,
and 6 color bits. The original commit adding support for BSS color
considered this to be a u8. This commit changes this to the actual
bits/values.
This adds an explicit config parameter for the partial bit. The disabled
is set to 0 implicitly if a bss_color is defined.
Interoperability testing showed that stations will require a BSS color
to be set even if the feature is disabled. Hence the default color is 1
when none is defined inside the config file.
