brcm2708: rename target to bcm27xx

This change makes the names of Broadcom targets consistent by using
the common notation based on SoC/CPU ID (which is used internally
anyway), bcmXXXX instead of brcmXXXX.
This is even used for target TITLE in make menuconfig already,
only the short target name used brcm so far.

Despite, since subtargets range from bcm2708 to bcm2711, it seems
appropriate to use bcm27xx instead of bcm2708 (again, as already done
for BOARDNAME).

This also renames the packages brcm2708-userland and brcm2708-gpu-fw.

+Subject: [PATCH] drm/vc4: Attach margin props to the HDMI connector
+
+Commit db999538fdb0679629d90652f8a1437df1e85a7d upstream.
+
+Now that the plane code takes the margins setup into account, we can
+safely attach margin props to the HDMI connector.
+
+We also take care of filling AVI infoframes correctly to expose the
+top/botton/left/right bar.
+
+Note that those margin props match pretty well the
+overscan_{left,right,top,bottom} properties defined in config.txt and
+parsed by the VC4 firmware.
