Patch Review

**Status: Looks good**

Adds `rk3576_edp` chip data and OF match table entry:

```c
static const struct rockchip_dp_chip_data rk3576_edp[] = {
    {
        .chip_type = RK3576_EDP,
        .reg = 0x27dc0000,
    },
    { /* sentinel */ }
};
```

The chip data intentionally omits `edp_mode` and `lcdc_sel` GRF fields. This is safe because `rockchip_grf_field_write()` checks `field->valid` (which defaults to `false` in zero-initialized structs) and returns 0 without writing. If RK3576 genuinely doesn't need GRF mode switching for eDP, this is correct. If it does need a GRF write that was overlooked, eDP would fail to initialize at runtime -- but this has Reviewed-by from two reviewers who presumably tested on hardware.

The OF match table entry is correctly sorted alphabetically between `rk3399-edp` and `rk3588-edp`.
