ARM: OMAP4: twl-common: Support for additional devices on i2c1 bus
On OMAP4 the i2c1 bus is dedicated for the PMIC and audio related devices. Manufacturers can opt to use different codec than twl6040 and also can add audio related IC to the bus (external amplifier for example on SDP4430). Make it possible to add different set of additional devices to i2c1 bus on OMAP4 boards.
