Hi Andi, Wolfram,
The Zhaoxin I2C controller uses the same I2C IP as Wonder Media.
Both Zhaoxin and Wonder Media's I2C IP are come from VIA I2C IP.
Therefore, some codes of i2c-wmt.c can be re-used by i2c-zhaoxin.c.
As suggested earlier, created two files, named i2c-viai2c-common.{c,h}.
They contains the macro definitions, functions declaration and data
structure used by both i2c-zhaoxin.c and i2c-wmt.c.
v1->v2:
1. Fixed a compilation error for header file references.
2. use I2C platform device's name to define the irq's name.

i2c: wmt: split out i2c-viai2c-common.{c,h}
i2c: add support for Zhaoxin I2C controller
