So, someone wants to come up with a patch to move to non-relaxed io

I could make the patch if we have consensus (or maintainers
decision) on which way to go: 1) only writes to DW_IC_INTR_MASK are
non-relaxed, 2) make all read/write accessors use the non-relaxed
version.
Fine with me, let's go for #2 :)
Also simplicity votes for #2.
+1 for the option #2. Let's do it and be finally over with this
patch.)

I think we have agreement to make the dw i2c driver regmap accessors use
the non-relaxed low-level functions, like writel instead of
writel_relaxed. These low level functions have memory barriers on
platforms that require them.
I'll work on a patch for this.
