From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>
Add clock and reset definitions required to support the DSI and LCDC
hardware blocks on the RZ/V2N SoC. This includes new core clocks, clock
dividers, module clocks, and reset entries, as well as PLL and divider
configurations specific to these peripherals.
