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] overlays: Make mcp342x run-time compatible
+
+The order of processing of run-time overlays differs from that done by
+the firmware. This means that certain parameter processing techniques
+are not compatible with run-time use.  The mcp342x overlay is one such
+overlay, but it is easy to change the implementation without changing
+the interface.
+
+See: https://www.raspberrypi.org/forums/viewtopic.php?f=107&t=258294
