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] drm/vc4: Make sure that vblank waits work without v3d
+ loaded.
+
+This flag exists to protect legacy drivers, but when vc4's v3d doesn't
+probe, it doesn't get set up by vc4_v3d.c's call of drm_irq_install.
+This resulted in applications running as fast as possible, and laggy
+performance from compton as it had to wait for the latest rendering by
+the application for its presentation.
