drm: renesas: rz-du: mipi_dsi: Use mHz for D-PHY frequency calculations

Browse source

Pass the HSFREQ in milli-Hz to the `dphy_init()` callback to improve
precision, especially for the RZ/V2H(P) SoC, where PLL dividers require
high accuracy.

These changes prepare the driver for upcoming RZ/V2H(P) SoC support.
