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] media: vb2: set reqbufs/create_bufs capabilities
+
+Upstream commit e5079cf11373e4cc98be8b1072aece429eb2d4d2.
+
+Set the capabilities field of v4l2_requestbuffers and v4l2_create_buffers.
+
+The various mapping modes were easy, but for signaling the request capability
+a new 'supports_requests' bitfield was added to videobuf2-core.h (and set in
+vim2m and vivid). Drivers have to set this bitfield for any queue where
+requests are supported.
