Add i2c new driver to support new register set for AST2600.
AST2600 support three modes for data transfer which are
byte mode, buffer mode and dma mode, respectively.
The global driver of i2c is used to set the new register
mode and define the base clock frequency
of baseclk_1~baseclk_4.

I commented _something_ (but read comments carefully, they will cover much
more). The overall it seems you have to:
 - shrink the code base by at least ~15% (it's possible), i.e. -200 LOCs
 - rethink how you do calculations and bit operations
 - better code style
