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.
