[PATCH v4 3/3] clk: imx: imx8qxp: add soft dependency on SCU power domain driver

[Zhipeng.wang_1@oss.nxp.com]

From: Zhipeng Wang <zhipeng.wang_1@nxp.com>

The i.MX8QXP SCU clock driver manually attaches power domains to each
clock device via of_genpd_add_device() in imx_clk_scu_attach_pd().
If the SCU power domain provider has not probed yet, the attachment
fails silently with a pr_warn() and the clock device is registered
without a power domain.

When both drivers are built as modules, there is no implicit
dependency to guarantee load order. Add MODULE_SOFTDEP("pre:
imx_scu_pd") so that modprobe loads the SCU power domain module
before the clock module.
