gpio/pch_gpio: Support new device ML7223
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. Signed-off-by: Tomoya MORINAGA <tomoya-linux@dsn.okisemi.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

This driver is for PCH(Platform controller Hub) GPIO of Intel Topcliff
which is an IOH(Input/Output Hub) for x86 embedded processor.
This driver can access PCH GPIO device.
