This adds the phy driver need for DSI output on rk3588.

The phy itself is used for both DSI output and CSI input, though the
CSI part for the whole chain needs a lot more work, so is left out for
now and only the DSI part implemented.

This allows the rk3588 with its current VOP support to drive a DSI display
using the DSI2 controller driver I'll submit in a next step.

Only generic phy interfaces are used, so the DSI part is pretty straight
forward.

changes in v2:
- fix error in dt-binding example
- drop unused frequency table
- pull in some more recent improvements from the vendor-kernel
  which includes a lot less magic values
- already include the support for rk3576
- use dev_err_probe
