Add DeLock-61959-support and add necessary patch to inihdp-3.14.2-kernel as example

Add necessary firmware-package
Add separate enigma2-plugins-drivers-dvb-usb-delock61959 virtual-package which install required firmware,modules and module config
The device requires a patch for the em28xx-module, which I added as example to the inihdp-3.14.2 kernel.
This is due to multpile i2c-device-support in the newer em28xx-module versions -- the chip used on that device has support for multiple i2c-bus, but uses one of them only and returns same IDs on i2c_read, which results in registering both i2c-busses using same sysfs-address which obviously segfaults.
Patch adds necessary module options to disable specific bus (in case of the delock the first bus has to be disabled) and the driver-virtual adds necessary module configs to /etc/modprobe.d/ and also disables ir for now. :+1: 
To DOs : 
check which kernels use same em28xx-module sources already, so kernel patch (and therefore support for the delock-package) may be added for more devices.
add pre-install check to enigma2-plugins-drivers-dvb-usb-delock61959 to make sure patched module is used.
add depend-block on the "normal" enigma2-plugins-drivers-dvb-usb-em28xx package, so that these packages cant be installed at the same time.
