[media] Add support for TechniSat Skystar S2
This patch adds support for the Technisat Skystar S2 - this has been tried before but the cx24120 driver was a bit out of shape and it didn't got any further: https://patchwork.linuxtv.org/patch/10575/ It is an old card, but currently being sold off for next to nothing, so it's proving quite popular of late. Noticing it's quite similar to the cx24116 and cx24117 I've rewritten the driver in a similar way. There were a few registers and commands from those drivers missing from this one I've tested out and found they do something so they've been added in to speed up tuning and to make get_frontend return something useful.
