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] staging: bcm2835-audio: Drop useless running flag and
+ check
+
+commit 02f2376321d75e78117f39ff81f215254ee6b4ef upstream.
+
+The running flag of alsa_stream is basically useless.  The running
+state is strictly controlled in ALSA PCM core side, hence the check in
+PCM trigger and close callbacks are superfluous.
+
+Also, the prefill ack at trigger start became superfluous nowadays
+with the ALSA PCM core update.
+
+Let's rip them off.
