ARM: OMAP2+: smsc911x: Remove regulator support from gmpc-smsc911x
Adding in support for regulators here creates several headaches. - Boards that declare their own regulator cannot use this function. - Multiple calls to this function require special handling. - Boards that declare id's other than '0' need special handling. Now that there is a simple regulator_register_fixed, we can push this registration back into the board files.
