staging: most: dim2: use dev_err_probe and proper error codes for clock

Replace hardcoded -EFAULT returns with dev_err_probe() and PTR_ERR()
when devm_clk_get() fails in fsl_mx6_enable(). This ensures the
correct error code is propagated (e.g. -EPROBE_DEFER for deferred
probing) and avoids log noise during probe deferral.
