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.

+ Using Overlays
+ ==============
+ 
+-Overlays are loaded using the "dtoverlay" directive. As an example, consider
+-the popular lirc-rpi module, the Linux Infrared Remote Control driver. In the
+-pre-DT world this would be loaded from /etc/modules, with an explicit
+-"modprobe lirc-rpi" command, or programmatically by lircd. With DT enabled,
+-this becomes a line in config.txt:
+-
+-    dtoverlay=lirc-rpi
+-
+-This causes the file /boot/overlays/lirc-rpi.dtbo to be loaded. By
+-default it will use GPIOs 17 (out) and 18 (in), but this can be modified using
+-DT parameters:
+-
+-    dtoverlay=lirc-rpi,gpio_out_pin=17,gpio_in_pin=13
+-
+-Parameters always have default values, although in some cases (e.g. "w1-gpio")
+-it is necessary to provided multiple overlays in order to get the desired
+-behaviour. See the list of overlays below for a description of the parameters
++Overlays are loaded using the "dtoverlay" config.txt setting. As an example,
++consider I2C Real Time Clock drivers. In the pre-DT world these would be loaded
++by writing a magic string comprising a device identifier and an I2C address to
++a special file in /sys/class/i2c-adapter, having first loaded the driver for
++the I2C interface and the RTC device - something like this:
++
++    modprobe i2c-bcm2835
++    modprobe rtc-ds1307
++    echo ds1307 0x68 > /sys/class/i2c-adapter/i2c-1/new_device
++
++With DT enabled, this becomes a line in config.txt:
++
++    dtoverlay=i2c-rtc,ds1307
++
++This causes the file /boot/overlays/i2c-rtc.dtbo to be loaded and a "node"
++describing the DS1307 I2C device to be added to the Device Tree for the Pi. By
++default it usees address 0x68, but this can be modified with an additional DT
++parameter:
++
++    dtoverlay=i2c-rtc,ds1307,addr=0x68
++
++Parameters usually have default values, although certain parameters are
++mandatory. See the list of overlays below for a description of the parameters
+ and their defaults.
