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 baudrate parameter to i2c3-i2c6
+
+The overlays for enabling the new BCM2711 I2C interfaces were lacking
+the means to configure the baud/clock rate.
+
+Also explictly set the default pins, rather than relying on the values
+in the base DTB.
