Claude review: drm/rockchip: analogix_dp: Add support for RK3576

Patch Review

Adds the platform-specific chip data and OF match entry:

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

**Key observation:** RK3576's chip data does not set `edp_mode` or `lcdc_sel` GRF fields, unlike RK3588 and the older SoCs. I verified that `rockchip_grf_field_write()` checks `!field->valid` and returns 0 early (at `analogix_dp-rockchip.c:107`), so the zero-initialized `edp_mode` field is safe -- the GRF write in `rockchip_dp_poweron()` and `rockchip_dp_powerdown()` will be a no-op. This implies RK3576 doesn't need an eDP mode GRF switch, which is plausible if the VO subsystem handles muxing differently.

Similarly, no `lcdc_sel` means the CRTC selection path in `rockchip_dp_drm_encoder_enable()` will skip the GRF write. This should be fine if RK3576 has a fixed eDP-to-CRTC mapping (no mux).

The OF table entry is correctly ordered alphabetically. The sentinel terminator is present.

**Overall:** This is a clean, well-organized series at v7 maturity. The RK3588 clock fix (patches 1-5) is a proper standalone fix with Fixes tags. The RK3576 support (patches 6-10) reuses the proven RK3588 code path with minimal additions. No correctness bugs found. The series is ready to merge.
