- Added dynamic scaler filter selection logic
- Added indirection layer for sub-core API's (picture settings,
PIP background color, debug information)
- Fixed VDMA alignment in 1/2/4 pixel configurations
- Added example directory. Included files to be uused with
vpss example design that will be released separately

-Updated driver structure, variable and API names to align with
defined coding guidelines
-Load scalers and chroma resampler coefficients only if the
instantiated configuration supports it

-Added logic to fix vdma ip alignement issues with different bit
width at axis and aximm interface at all supported pixel/clk
and color depth combinations
-Moved stream (input/output) validation logic scattered around
in different blocks to a central location
-Added API to report subsystem configuration status
-Code cleanup and changed relevant prints to dbg print

- Code cleanup to remove interrupt handler registration.
Subsystem does not have interrupts
- Updated sub-core init routines to load default filter
coefficients for scaler and chroma resamplers
- Added layer 2 registers for chroma resamplers
- Updated VDMA Read/Write interface to work with color depth
instead of Bytes/Pixel

This patch supports HIP based video processing subsystem.
Added makefile and tcl to build the subsystem tree and updated
the driver to construct sub-core baseaddress

Video processing subsystem driver is added to the repo. This
driver currently is associated with a non-HIP version of the
IP. No makefile available. Hard-coded g.c file used, but not
included.
