The omap24xx I2C driver uses its own CONFIG namespace for common I2C variables. Rather than convert more of them to Kconfig, rename these to the common I2C ones and remove the entirely unused functionality. As part of this, we make the am335x_shc platforms consistent with their intended speed values. Signed-off-by: Tom Rini <trini@konsulko.com>
