BCM2708: Add Raspberry Pi TV HAT Device Tree Support 



This is an EXAMPLE CODE of Raspberry Pi TV HAT device tree overlay.
Although this is not a part of our release code, it has been used to verify
CXD2880 device driver with TV HAT.

Add the following line to /boot/config.txt to enable TV HAT:

dtoverlay=rpi-tv

Reboot Raspberry Pi and check the existance of /proc/device-tree/soc/spi@7e204000/cxd2880@0.
If exists, the installation is successful.  you should be able to find the following three files.
/dev/dvb/adapter0/frontend0
/dev/dvb/adapter0/demux0
/dev/dvb/adapter0/dvr0
