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: audremap: Support GPIOs 18 & 19
+
+PWM audio can also be used on GPIOs 18 and 19, so add the pins_18_19
+parameter to select that location. pins_12_13 explicitly chooses GPIOs
+12 and 13, although this is the default behaviour so is there only for
+completeness.
+
+See: https://github.com/raspberrypi/firmware/issues/1178
