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: Add non-removable clone of mmc node
+
+non-removable is a boolean property, and as such can't be unset by an
+overlay if it is set in a base DTB. Until now the workaround for this
+problem has been for overlays to clone non-removable nodes without
+the offending property, but this involves a lot of unnecessary
+replication. Instead, add a clone of the mmc node with non-removable
+already set to the base DTB, selecting the required version using
+the status properties.
