[PATCH V2 5/5] pch_dma: Support new device ML7223 IOH

[Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com>]

Support new device OKI SEMICONDUCTOR ML7223 IOH(Input/Output Hub).
The ML7223 IOH is for MP(Media Phone) use.
The ML7223 is companion chip for Intel Atom E6xx series.
The ML7223 is completely compatible for Intel EG20T PCH.
