[media] au0828: move the code that sets DTV on a separate function
As we'll be adding a code to resume tuner operation, we need to move the code that actually sets DTV on a separate function, to be called by the resume code. No functional changes, just code got moved. Signed-off-by: Mauro Carvalho Chehab <m.chehab@samsung.com>
