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: Fix warning about vblank interrupts before
+ DRM core is ready.
+
+The SMICS interrupt fires continuously, but since it's 1/100 the rate
+of the USB interrupts, we don't really need a way to turn it off.  We
+do need to make sure that we don't tell DRM about it until DRM has
+asked for the interrupt at least once, because otherwise it will throw
+a warning at boot time.
