media: dvb/earth-pt1: fix wrong initialization for demod blocks
earth-pt1 driver was decomposed/restructured by the commit b732539efdba ("media: dvb: earth-pt1: decompose pt1 driver into sub drivers"), but it introduced a problem regarding concurrent streaming: Opening a new terrestial stream stops the reception of an existing, already-opened satellite stream. The demod IC in earth-pt1 boards contains 2 pairs of terr. and sat. blocks, supporting 4 concurrent demodulations, and the above problem was because the config of a terr. block contained whole reset/init of the pair blocks, thus each open() of a terrestrial frontend wrongly cleared the config of its peer satellite block of the demod. This whole/pair reset should be executed earlier and not on each open().
