pinctrl: imx-scmi: Drop obsolete dependency on COMPILE_TEST

Since commit 0166dc11be91 ("of: make CONFIG_OF user selectable"), OF
can be enabled on all architectures. Therefore depending on
COMPILE_TEST as an alternative is no longer needed.

As ARM_SCMI_PROTOCOL already depends on COMPILE_TEST, we also don't
need to add COMPILE_TEST as an alternative dependency for it.
