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] ASoC: pcm512x: Implement the digital_mute interface
+
+[ Upstream commit 3500f1c589e92e0b6b1f8d31b4084fbde08d49cb ]
+
+Clicks and pops of various volumes can be produced while the device is
+opened, closed, put into and taken out of standby, or reconfigured.
+Fix this, by implementing the digital_mute interface, so that the
+output is muted during such operations.
