core_dll_config is very much used. But having a local for it feels like
a bad idea. As different versions come up, the most used register may
change. So it would be better to stick to a consistent approach to
accessing every register.

if we use a helper function, then we will have to pass msm_host into it
as well. Otherwise there would be the hassle of deriving msm_host
address from sdhci_host.
How about using a MACRO here instead for readability ?
