Adrian Schmutzler 7d7aa2fd92 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] bcm2838.dtsi: Use BCM2711 PCIe compatible string
The BCM2711 PCIe controller has a limited address range in the B0
silicon, and the driver uses a compatible string to identify the
limitation. The current Pi 4 firmware will override the compatible
string if it detects a downstream DTB and it is running on a newer
revision but set the default value to enable the workaround for
backwards-compatibility with old firmware.
