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: Add "Broadcast RGB" connector property
-
-Some HDMI monitors do not abide by the full or limited
-(16-235) range RGB flags in the AVI infoframe. This can
-result in images looking washed out (if given limited and
-interpreting as full), or detail disappearing at the extremes
-(given full and interpreting as limited).
-
-Copy the Intel i915 driver's approach of adding an override
-property ("Broadcast RGB") to force one mode or the other.
