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] staging: mmal-vchiq: Always return the param size
+ from param_get
+
+mmal-vchiq is a reimplementation of the userland library for MMAL.
+When getting a parameter, the client provides the storage and
+the size of the storage. The VPU then returns the size of the
+parameter that it wished to return, and as much as possible of
+that parameter is returned to the client.
+
+The implementation previously only returned the size provided
+by the VPU should it exceed the buffer size. So for parameters
+such as the supported encodings list the client had no idea
+how much of the provided storage had been populated.
