saa7115: fix saa7111(a) support
From: Hans Verkuil <hverkuil@xs4all.nl> The saa7111 support in saa7115.c was missing some features and did not properly take some of the differences into account. With this patch saa7115 can be used in the mxb driver instead of saa7111.c. Priority: normal Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl>
