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] Add support for Fe-Pi audio sound card. (#1867)
+
+Fe-Pi Audio Sound Card is based on NXP SGTL5000 codec.
+Mechanical specification of the board is the same the Raspberry Pi Zero.
+3.5mm jacks for Headphone/Mic, Line In, and Line Out.
