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 negative X/Y positioning on SAND planes
+
+Commit 8e75d582db02bcb171d65ec71eecbd3072a5fd3a upstream.
+
+Commit 3e407417b192 ("drm/vc4: Fix X/Y positioning of planes using
+T_TILES modifier") fixed the problem with T_TILES format, but left
+things in a non-working state for SAND formats. Address that now.
