intel/common/block/i2c: Add common block for I2C and use the same in SoCs

Browse Source 
In the intel/common/block
* Move I2C common code from intel/common to intel/common/block.
* Split the code into common, early init and post mem init stages and put it
  in lpss_i2c.c, i2c_early.c and i2c.c respectively.
* Declare functions for getting platform specific i2c bus config and
  mapping bus to devfn and vice versa, that have to be implemented by SoC.

In skylake/apollolake
* Stop using code from soc/intel/common/lpss_i2c.c.
* Remove early i2c initialization code from bootblock.
* Refactor i2c.c file to implement SoC specific methods
  required by the I2C IP block.
