base on DesignWare I2C driver to implement RTS5912 I2C driver. 1. support customize bus recovery function. 2. fix isr timing issue by enable tx empty control. 3. support stuck at low handle by enable bus clear feature. 4. support custom stuck at low timeout set from dts 5. disable block mode in rts5912 i2c. 6. support I2C_ALLOW_NO_STOP_TRANSACTIONS Signed-off-by: Titan Chen <titan.chen@realtek.com>
