Add OSD block changes to enable dm365 and dm355 for vpbe driver.
Changes are based on version number of OSD, which have incremental
changes over 644x OSD hardware interms of few registers.

VPBE_VERSION_2 = dm365 specific
VPBE_VERSION_3 = dm355 specific

This patch implements the core additions to the display driver,
mainly controlling the VENC and other encoders for dm365.
This patch also includes addition of amplifier subdevice to the
vpbe driver and interfacing with venc subdevice.

In the original code, probe_out could be reached when res was null and then
when the irq had not yet been requested.  In those cases, the call to
free_irq is not needed, so move probe_out down and introduce a new label
for the case where calling free_irq is useful.

Standardize the remaining video drivers to return the API version
for the VIDIOC_QUERYCAP version, instead of a per-driver version.

Those drivers had the version updated more recently or are SoC
drivers. Even so, it doesn't sound a good idea to keep a per-driver
version control, so, let's use the per-subsystem version control
instead.

This patch adds the VENC or the Video encoder, which is responsible
for the blending of all source planes and timing generation for Video
modes like NTSC, PAL and other digital outputs. the VENC implementation
currently supports COMPOSITE and COMPONENT outputs and NTSC and PAL
resolutions through the analog DACs. The venc block is implemented
as a subdevice, allowing for additional external and internal encoders
of other kind to plug-in.

This patch implements the functionality of the OSD block
of the VPBE. The OSD in total supports 4 planes or Video
sources - 2 mainly RGB and 2 Video. The patch implements general
handling of all the planes, with specific emphasis on the Video
plane capabilities as the Video planes are supported through the
V4L2 driver.

This is the display driver for Texas Instruments's DM644X family
SoC. This patch contains the main implementation of the driver with the
V4L2 interface. The driver implements the streaming model with
support for both kernel allocated buffers and user pointers. It also
implements all of the necessary IOCTLs necessary and supported by the
video display device.

With the v4l2_i2c_new_subdev* functions now supporting loading modules
based on modaliases, don't use the module names hardcoded in platform
data by passing a NULL module name to those functions.

The only platform using the VPIF capture device (DM646x EVM) hardcodes
the module names to invalid values (tvp514x-0 and tvp514x-1). As this is
already broken, there's no risk of breaking it more.

v4l2_prio_init/open/close returned an int when in fact they would
always return 0. Make these void functions.

v4l2_prio_close and v4l2_prio_check pass an enum v4l2_priority as a
pointer for no good reason. Replace with a normal enum v4l2_priority
argument.

These changes will simplify the work of moving priority handling into
the v4l core.
