Subject: [PATCH v3 15/15] drm: renesas: rz-du: mipi_dsi: Add support for RZ/V2H(P) SoC

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>

Add DSI support for Renesas RZ/V2H(P) SoC.

Co-developed-by: Fabrizio Castro <fabrizio.castro.jz@...esas.com>
Signed-off-by: Fabrizio Castro <fabrizio.castro.jz@...esas.com>
Signed-off-by: Lad Prabhakar <prabhakar.mahadev-lad.rj@...renesas.com>
---
v2->v3:
- Simplifed V2H DSI timings array to save space
- Switched to use fsleep() instead of udelay()

v1->v2:
- Dropped unused macros
- Added missing LPCLK flag to rzvv2h info
