V4L/DVB (5129): M920x: break out qt1010 tuner code into a separate file
qt1010 is a tuner used in some other devices, so this code should be put into a separate file so that it could be reused by other drivers. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
