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 NULL pointer dereference in the async
+ update path
+
+vc4_plane_atomic_async_update() calls vc4_plane_atomic_check()
+which in turn calls vc4_plane_setup_clipping_and_scaling(), and since
+commit 58a6a36fe8e0 ("drm/vc4: Use
+drm_atomic_helper_check_plane_state() to simplify the logic"), this
+function accesses plane_state->state which will be NULL when called
+from the async update path because we're passing the current plane
+state, and plane_state->state has been assigned to NULL in
+drm_atomic_helper_swap_state().
+
+Pass the new state instead of the current one (the new state has
+->state set to a non-NULL value).
+
+Fixes: 58a6a36fe8e0 ("drm/vc4: Use drm_atomic_helper_check_plane_state() to simplify the logic")
