Update copyright comments after dvb-usb-v2 conversion.
Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

The dvb-usb-v2 core doesn't know anything about CI. So, the
driver needs to handle it by hand. This patch stops CI just
before stopping URB's/RC, and restarts it before URB/RC start.

It should be noticed that suspend/resume is not yet working properly,
as the PM model requires the implementation of reset_resume:
	dvb_usb_az6007 1-6:1.0: no reset_resume for driver dvb_usb_az6007?
But this is not implemented there at dvb-usb-v2 yet.

The dvb-usb-v2 cypress firmware module is not optional, as drivers
won't work without it. So, instead of opening a menu for the user to
manually select, let the drivers that need it to select, hiding this
option from the Kconfig menu.

Some video decoders such as tvp5150 provide separate
video fields (V4L2_FIELD_SEQ_TB/BT). This driver uses
dmaengine to convert this format to V4L2_FIELD_INTERLACED_TB/BT
(weaving) or V4L2_FIELD_NONE (line doubling) so that the
image can be displayed or processed.

Of course there will be combing effect in the image but this
can be accepted for some low quality applications.

Currently only YUV420 and YUYV formats are supported but
it can be extended later.
