i2c-designware: Push all register reads/writes into the core code.
Move all register manipulation code into the core, also move register
offset definitions to i2c-designware-core.c since the bus specific
portions of the driver no longer need/use them.

i2c-designware: move controller config to bus specific portion of driver
With multiple I2C adapters possible in the system each running at
(possibly) different speeds we need to move the controller
configuration bit field to the adapter.

i2c-designware: move i2c functionality bit field to be adapter specific
The functionality of the adapter depends on the configuration of the
IP block at silicon compile time and is adapter specific.

i2c-designware: Move retriveving the clock speed out of core code.
The clock frequecy supplied to the IP core is specific to a single
instance of the driver. This patch makes it possible to have multiple
Designware I2C cores in the system possibly running at different core
frequencies.

i2c-designware: split of i2c-designware.c into core and bus specific parts
This patch splits i2c-designware.c into three pieces:
i2c-designware-core.c, contains the code that interacts directly
with the core.
i2c-designware-platdrv.c, contains the code specific to the
platform driver using the core.
i2c-designware-core.h contains the definitions and declareations
shared by i2c-designware-core.c and i2c-designware-platdrv.c.
This patch is the first in a set to allow multiple instances of the
designware I2C core in the system.
