It works at my side because it can manually selected as m or add CONFIG_MXC_CLK=m
In defconfig.
But now I got your point you want CONFIG_MXC_CLK default to m once define
CONFIG_CLK_IMX8X=m in defconfig.

I just noticed for MX6&7, actually CONFIG_MXC_CLK can't be m otherwise we will meet build break.
That means CONFIG_MXC_CLK cannot be configurable by users for non-ARM64 platforms.
Thus can't use def_tristate and we still need select it under ARCH_MXC.
This lightly lose a bit meaning to make this core library as module.
IMHO I'd still prefer to builtin those core libraries rather than convert to module.
