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