[media] media: venus: adding core part and helper functions
* core.c has implemented the platform driver methods, file operations and v4l2 registration. * helpers.c has implemented common helper functions for: - buffer management - vb2_ops and functions for format propagation, - functions for allocating and freeing buffers for internal usage. The buffer parameters describing internal buffers depends on current format, resolution and codec. - functions for calculation of current load of the hardware. Depending on the count of instances and resolutions it selects the best clock rate for the video core. * firmware loader Signed-off-by: Stanimir Varbanov <stanimir.varbanov@linaro.org> Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@s-opensource.com>
