Copy missing Kernel patch to make SLEWCTRL_SLOW available in device tree and to correct the value of SLEWCTRL_FAST. After this patch, the Kernel and U-boot device tree settings for SLEWCTRL have the same effect. Original Kernel patch message: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=424e0f039bfa8a51fb5c5178b6ece8baa4996469 " 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.
