Subject: [PATCH v6 0/4] Add features to an existing driver

The wave5 codec driver is a stateful encoder/decoder.
The following patches is for supporting yuv422 inpuy format,
supporting runtime suspend/resume feature and extra things.

v4l2-compliance results:
========================

v4l2-compliance 1.24.1, 64 bits, 64-bit time_t

Buffer ioctls:
       warn: v4l2-test-buffers.cpp(693): VIDIOC_CREATE_BUFS not supported
       warn: v4l2-test-buffers.cpp(693): VIDIOC_CREATE_BUFS not supported
    test VIDIOC_REQBUFS/CREATE_BUFS/QUERYBUF: OK
    test VIDIOC_EXPBUF: OK
    test Requests: OK (Not Supported)

Total for wave5-dec device /dev/video0: 45, Succeeded: 45, Failed: 0, Warnings: 2
Total for wave5-enc device /dev/video1: 45, Succeeded: 45, Failed: 0, Warnings: 0

Fluster test results:
=====================

Running test suite JCT-VC-HEVC_V1 with decoder GStreamer-H.265-V4L2-Gst1.0 Using 1 parallel job(s)
Ran 132/147 tests successfully               in 88.745 secs

(1 test fails because of not supporting to parse multi frames, 1 test fails because of a missing frame and slight corruption,
 2 tests fail because of sizes which are incompatible with the IP, 11 tests fail because of unsupported 10 bit format)

Running test suite JVT-AVC_V1 with decoder GStreamer-H.264-V4L2-Gst1.0 Using 1 parallel job(s)
Ran 77/135 tests successfully               in 32.044 secs

(58 fail because the hardware is unable to decode  MBAFF / FMO / Field / Extended profile streams.)

Change since v0:
=================
The DEFAULT_SRC_SIZE macro was defined using multiple lines, To make a simple define, tab and multiple lines has been removed, The macro is defined using one line.
