Adrian Schmutzler 7d7aa2fd92 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] media: adv7180: Nasty hack to allow input selection.
Whilst the adv7180 driver support s_routing, nothing else
does, and there is a missing lump of framework code to
define the mapping from connectors on a board to the inputs
they represent on the ADV7180.
Add a nasty hack to take a module parameter that is passed in
to s_routing on any call to G_STD, or S_STD (or subdev
g_input_status call).
