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: Fix draining behavior
+ regression
+
+The PCM draining behavior got broken since the recent refactoring, and
+this turned out to be the incorrect expectation of the firmware
+behavior regarding "draining".  While I expected the "drain" flag at
+the stop operation would do processing the queued samples, it seems
+rather dropping the samples.
+
+As a quick fix, just drop the SNDRV_PCM_INFO_DRAIN_TRIGGER flag, so
+that the driver uses the normal PCM draining procedure.  Also, put
+some caution comment to the function for future readers not to fall
+into the same pitfall.
+
+Fixes: d7ca3a71545b ("staging: bcm2835-audio: Operate non-atomic PCM ops")
