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] cpufreq: add driver for Raspberry Pi
-
-Commit d3df18a97e586702920337056540267807b23f8e upstream.
-
-Raspberry Pi's firmware offers and interface though which update it's
-performance requirements. It allows us to request for specific runtime
-frequencies, which the firmware might or might not respect, depending on
-the firmware configuration and thermals.
-
-As the maximum and minimum frequencies are configurable in the firmware
-there is no way to know in advance their values. So the Raspberry Pi
-cpufreq driver queries them, builds an opp frequency table to then
-launch cpufreq-dt.
-
-Also, as the firmware interface might be configured as a module, making
-the cpu clock unavailable during init, this implements a full fledged
-driver, as opposed to most drivers registering cpufreq-dt, which only
-make use of an init routine.
