[PATCH 16/16] i2c-designware: Add I2C_FUNC_SMBUS_* bits
From: Shinya Kuribayashi <hidden>

Subsystem:

Andi Shyti, Linus Torvalds
This will ease our testing a bit with i2c-tools. Note that DW I2C core doesn't support I2C_FUNC_SMBUS_QUICK, as it's not capable of slave- addressing-only I2C transactions.
