[media] technisat-usb2: added driver for Technisat's USB2.0 DVB-S/S2 receiver
This patch is adding support for Technisat's new USB2.0 DVB-S/S2 receiver device. The development was sponsored by Technisat. The Green led is toggle depending on the frontend-state. The Red LED is turned on all the time. The MAC address reading from the EEPROM along with the LRC-method to check whether its valid. Support for the IR-receiver of the Technisat USB2 box. The keys of small, black remote-control are built-in, repeated key behaviour are simulated. The i2c-mutex of the dvb-usb-structure is used as a general mutex for USB requests, as there are 3 threads racing for atomic requests consisting of multiple usb-requests. A module option is there which disables the toggling of LEDs by the driver on certain triggers. Useful when being used in a "dark" environment.
