V4L/DVB (4592): Fixes some troubles on saa7115
Scaling were not working fine; Some reserved registers were wrong; On some situations, saa7115 were not properly being initializated. Removed some duplicated code. Thanks-to: Hans Verkuil <hverkuil@xs4all.nl> for co-working on this patch. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
