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] amba_pl011: Don't use DT aliases for numbering
+
+The pl011 driver looks for DT aliases of the form "serial<n>",
+and if found uses <n> as the device ID. This can cause
+/dev/ttyAMA0 to become /dev/ttyAMA1, which is confusing if the
+other serial port is provided by the 8250 driver which doesn't
+use the same logic.
