Changes since V5: - make i.MX ARMv7 platforms clock driver to bool and NOT support COMPILT_TEST, since they depends on ARCH_MXC or SOC config, which makes the COMPILT_TEST NOT make enough sense, so just skip the COMPILT_TEST support for i.MX ARMv7 platform clock drivers, leave them same as original implementation. - add a patch to fix build warning reported by kernel robot test on i.MX6SL clock driver.
