wifi: cfg80211: Update the default DSCP-to-UP mapping

The default DSCP-to-UP mapping method defined in RFC8325
applied to packets marked per recommendations in RFC4594 and
destined to 802.11 WLAN clients will yield a number of inconsistent
QoS mappings.

To handle this, modify the mapping of specific DSCP values for
which the default mapping will create inconsistencies, based on
the recommendations in section 4 in RFC8325.

Note: RFC8235 is used as it referenced by both IEEE802.11Revme_D4.0
and WFA QoS Management Specification.
