Although sc7180 is supposed to have a hardware fix that means that we don't have to restore the DLL config like we did with sdm845, apparently the hardware fix doesn't work in all cases. Until it's understood under exactly which cases we the hardware fix malfunctions, let's go back to restoring the DLL config whenever we do runtime resume. This is safe and gets things working again. NOTE: we don't need to introduce a whole new "struct sdhci_msm_variant_info" for sc7180 since it would be exactly the same as the sdm845 one. We'll just refer to that one.
