From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Update the driver to obtain the "oscclk" clock using devm_clk_get_optional_prepared() instead of devm_clk_get_prepared(). This allows the driver to handle cases where the "oscclk" clock is not present in the hardware or device tree. This change is in preparation for adding support for the RZ/T2H SoC, which does not provide the "oscclk" clock.
