media: chips-media: wave5: Use helpers to calculate bytesperline and sizeimage.

Use v4l2-common helper functions to calculate bytesperline and sizeimage,
instead of calculating in a wave5 driver directly.

In case of raw(YUV) v4l2_pix_format, the wave5 driver updates
v4l2_pix_format_mplane struct through v4l2_fill_pixfmt_mp() function.

Encoder and Decoder need the same bytesperline and sizeimage values for
the same v4l2_pix_format. So, wave5_update_pix_fmt function is refactored
to support both together.
