ARM: dts: dra72-evm: Enable I2C1 node

I2C1 bus is used for the following peripherals
	P8 connector (MLB)
	TLV320AIC3106 Audio codec
	J15 LCD header
	24WC256 eeprom
	TMP102AIDRLT temperature sensor
	PCF8575 GPIO expander
	PCA9306 i2c voltage translator -> Goes to P9 for comm interface
	P2 expansion connector
	TPS65917 PMIC

The slowest speed of all the peripherals seems to be 400KHz.
