Claude review: drm/rockchip: dw_hdmi: Use of_device_get_match_data() to get match data

[Claude Code Review Bot <claude-review@example.com>]

Patch Review

**Status: Clean**

This replaces `of_match_node()` + `match->data` with the simpler `of_device_get_match_data()`. The early NULL check before allocation is a good improvement -- if the match table entry somehow lacks data, we bail before allocating.

The `sizeof(*drv_data)` in the `devm_kmemdup` call is correct since `drv_data` is `const struct dw_hdmi_plat_data *`, same type as the old `sizeof(*plat_data)`.

The removal of the `struct device_node *np = dev_of_node(dev)` variable is not done here but `np` is still used later, and the `of_device_get_match_data()` takes `dev` directly rather than `np`. The `np` NULL check remains, which is fine since it's used elsewhere.

No issues.
