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: Fix multiple-instantiation of sc16is7xx*
+
+The registration of the fixed clocks uses the node name as the clock
+name, causing a clash if two clock nodes have the same name, regardless
+of the path to the node. Fix the issue by overwriting the clock node
+names using the value of the "addr" parameter, providing a crude
+disambiguation. (A bit of string pasting to form "sc16is752_clk_<addr>"
+would have been nice, but that is outside the abilities of the overlay
+parameter mechanism.)
+
+Also give the sc16is750-i2c overlay the xtal parameter for symmetry.
+
+See: https://www.raspberrypi.org/forums/viewtopic.php?f=107&t=235650
