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] staging: vcsm-cma: Remove cache manipulation ioctl
+ from ARM64
+
+The cache flushing ioctls are used by the Pi3 HEVC hw-assisted
+decoder as it needs finer grained flushing control than dma_ops
+allow.
+These cache calls are not present for ARM64, therefore disable
+them. We are not actively supporting 64bit kernels at present,
+and the use case of the HEVC decoder is fairly limited.
