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] overlays: Add i2c0 and i2c1 for regularity
+
+The new i2c overlays for pi4 (i2c3, i2c4, i2c5, i2c6) have a
+standardised interface that allows pin groups to be chosen
+atomically rather than as individual pins. Add i2c0 and i2c1
+overlays to fit the naming scheme and parameter usage, deprecating
+i2c0-bcm2708 and i2c1-bcm2708.
