I'll re-send the remaining interconnect patches soon.

Perhaps will be better to drop these memory changes for now from this
series since they are optional, i.e. memory drivers will work properly
because voltage changes are done by the OPP core and these patches just
replace the duplicated code with a new common helper which doesn't add
new features to the memory drivers. It should be fine to get back to
these memory patches once interconnect patchset will be fully merged.
I'll take it into account in v3, thanks.
