Is this a backwards-compatible change? Or it's not really worth to care
about the compatibility with older kernel versions, I'm not sure about
overall state of T210 in the upstream kernel.
I don't think its required to be backwards-compatible as SC7 entry/exit
implementation for T210 is with this patch series onwards..
