southbridge/intel/common/smbus.c: Add support for I2C block write

Intel Braswell supports communication with I2C device using SMBus controller.
This support is missing in actual smbus routines.

Add:
- i2c_block_write()
- do_i2c_block_write()

i2c_block_write() configures SMBus controller in I2C mode
before calling do_i2c_block_write().
do_i2c_block_write() sends the block writes in I2C mode.

BUG=N/A
TEST=LCD display on Facebook FBG-1701
