soc/intel/braswell: Add SMBus support

Intel Braswell SoC contains SMBus controller but no support
is available for this controller.
This controller is compatible with the Intel SMBus support in the
southbridge common directory.

To be able using smbus support from the Intel common directory
the smbus.c is moved outside SOUTHBRIDGE_INTEL_COMMON
dependency block.
Use SOUTHBRIDGE_INTEL_COMMON_SMBUS to include support.

BUG=N/A
