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 sending of page flip completion events
+ in FKMS mode.
+
+In the rewrite of vc4_crtc.c for fkms, I dropped the part of the
+CRTC's atomic flush handler that moved the completion event from the
+proposed atomic state change to the CRTC's current state.  That meant
+that when full screen pageflipping happened (glxgears -fullscreen in
+X, compton, por weston), the app would end up blocked firever waiting
+to draw its next frame.
