No, that's completely broken.  We can't do a raw read from a regmap that
doesn't offer raw access and we shouldn't pretend to do so.  If the
caller is capable of substituting a register by register read the caller
should take responsibility for that.

So can regcache initialization be changed to use register by register read
in case raw read fails?

Well, we *do* have full source code access!  I'm just blind writing a
patch to do that.
