According to AM335x TRM, Document spruh73l, Revised February 2015, Section 9.2.2 Pad Control Registers, setting bit 6 of the pad control registers actually sets the SLEWCTRL value to slow rather than fast as the current macro indicates. Introduce a new macro, SLEWCTRL_SLOW, that sets the bit, and modify SLEWCTRL_FAST to 0 but keep it for completeness. Current users of the macro (i2c and mdio) are left unmodified as SLEWCTRL_FAST was the macro used and actual desired state. Tested on am335x-gp-evm with no difference in software performance seen.
