From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> The RZ/V2H(P) SoC does not provide a `system` clock for the CSI-2 interface. To accommodate this, use `devm_clk_get_optional()` instead of `devm_clk_get()` when retrieving the clock. This patch is in preparation for adding support for RZ/V2H(P) SoC.
