V4L/DVB (5137): Dvb: add new qt1010 tuner module
QT1010: - old qt1010-code totally rewritten and put in own kernel module - same enhancements as my earlier QT1010 125kHz patch - tuner initialization - register 1f calculation - register 20 calculation - register 25 calculation m920x: (MSI Megasky) - use new QT1010 module instead of old code Signed-off-by: Antti Palosaari <crope@iki.fi> Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
