arm64: DTS: rk3399-puma.dts: Update DMC OPs.
Extending the operating point list of the DMC to include frequencies of up to 800 MHz. This increases bandwidth and fixes issues observed with RKISP1 (PIC_SIZE_ERRORs when performing memory intensive tasks in parallel). Signed-off-by: Christoph Muellner <christoph.muellner@theobroma-systems.com>
