Merge branch 'sandbox/ronan/rocko_kf'

Add Kingfisher board support for AGL master

* Currently the renesas 3.4 BSP support, for Kingfisher,
   is provided by Cogent.
 https://github.com/Cogenh3ulcbtEmbedded/meta-rcar

* Add cogent BSP for h3ulcb, m3ulcb, m3ulcb-nogfx
* Update BBMASK for gen3 board
* Backport Matt Porter fix "preserve drm HDMI connector naming"
* ti-bt: add a systemd unit and enable
* ulcb: Disable build-in most driver
* si-tools: FM configuration improvements

Bug-AGL: SPEC-1175

+FM configuration improvements
+
+Changes include:
+- Add command-line option for selecting FM band plan.  The default
+  band plan is US / Canada.
+- Add command-line options for setting FM scanning valid SNR and RSSI
+  thresholds to allow tweaking sensitivity in poor radio environments.
+- Increased seeking scan timeout to 3 seconds, which seems to improve
+  behavior in poor radio environments where powerful stations may be
+  far apart.
+- Removed explicit setting of FM_SOFTMUTE_SNR_LIMITS, as it seemed
+  like it might be resulting in odd muting behavior when scanning.
+- Changed initial FM frequency if not specified to the minimum of the
+  band plan.
