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: tc358743: Return an appropriate colorspace
+ from tc358743_set_fmt
+
+When calling tc358743_set_fmt, the code was calling tc358743_get_fmt
+to choose a valid format. However that sets the colorspace
+based on what was read back from the chip. When you set the format,
+then the driver would choose and program the colorspace based
+on the format code.
+
+The result was that if you called try or set format for UYVY
+when the current format was RGB3 then you would get told sRGB,
+and try RGB3 when current was UYVY and you would get told
+SMPTE170M.
+
+The value programmed into the chip is determined by this driver,
+therefore there is no need to read back the value. Return the
+colorspace based on the format set/tried instead.
