MLK-17362-01 Changes for wireless and cfg80211 support

[Patch] Pulling the following commits and some general changes
from custom v3.10 kernel for supporting qcacld2.0 on kernel v4.9.11.
1. cfg80211: Using new wiphy flag WIPHY_FLAG_DFS_OFFLOAD
When flag WIPHY_FLAG_DFS_OFFLOAD is defined, the driver would handle
all the DFS related operations. Therefore the kernel needs to ignore
the DFS state that it uses to block the userspace calls to the driver
through cfg80211 APIs. Also it should treat the userspace calls to
start radar detection as a no-op.

Please note that changes in util.c is not picked up explicitly.
Kernel v4.9.11 uses wrapper cfg80211_get_chans_dfs_required which takes
care of this change.

Change-Id: I9dd2076945581ca67e54dfc96dd3dbc526c6f0a2
IRs-Fixed: 202686

2. New db.txt from git/sforshee/wireless-regdb.git
CONFIG_CFG80211_INTERNAL_REGDB is enabled in build. This causes
kernel warn messages as db.txt is empty. A new db.txt is added
from:
git://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git

IRs-Fixed: 202686

3. Picked up the declaration and definition of the function
cfg80211_is_gratuitous_arp_unsolicited_na

+# The values for the 5 GHz have been reduced by a factor of 2 (3db) for non TPC
+# devices (in other words: devices with TPC can use twice the tx power of this

+# to 100mW thus is not strictly required -- however the conservative 100mW
+# limit is used here as the non-interference with radar and satellite
+# apps relies on the attenuation by the building walls only in the
+# absence of DFS; the neighbour countries have 100mW limit here as well.
