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] BCM270X_DT: Rename Pi Zero W DT files
+
+The downtream Pi Zero W dts file uses the digit 0, whereas upstream
+chose to spell it out - "zero-w". The firmware has, for a long time,
+looked for bcm2708-rpi-zero-w.dtb first before falling back to the
+numerical version. Therefore it is better to follow upstream and
+make the switch to "bcm2708-rpi-zero-w".
+
+At the same time, remove some overrides that duplicate values
+inherited from the shared .dtsi files.
