media: rockchip: rga: split src and dst buffer setup

Split the register setup for the source and destination video buffers
into separate functions.

This is a cleanup to make the code more readable by separating the
offset calculation for the different buffers and prepares the driver for
using pre-calculated offsets of planes.
