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] bcmgenet: Better coalescing parameter defaults
+
+Set defaults for TX and RX packet coalescing to be equivalent to:
+
+  # ethtool -C eth0 tx-frames 10
+  # ethtool -C eth0 rx-usecs 50
+
+This may be something we want to set via DT parameters in the
+future.
