drm/rockchip: dsi: Add dphy_get_timing support for multiple PHY types

Browse source

Currently, there are generally two types of DPHY for Rockchip. One is
the DPHY used by RK3288/RK3399, whose timing is described by Table A-3
High-Speed Transition Times in the databook. The other is the DPHY used
by PX30 and its successors. If its timing is still described using
RK3288/RK3399, it may not perform correctly on some DSI panel.

Add dphy_get_timing for different D-PHY types to adapt to timing
differences. The configuration details are as follows:

- RK3288/RK3399: Select the corresponding entry from the timing table based
                 on the data rate.
- PX30 and later platforms: Use a fixed timing configuration.
