Fix clock rate setting in the mxs-mmc driver. Previously, if div2 was 0 then the value for TIMING_CLOCK_RATE would have been 255 instead of 0. The limits for div1 (TIMING_CLOCK_DIVIDE) and div2 (TIMING_CLOCK_RATE+1) were also not correctly defined. Can easily be reproduced on mx23evk: default clock for high speed sdio cards is 50 MHz. With a SSP_CLK of 28.8 MHz default), this resulted in an actual clock rate of about 56 kHz. Tested on mx23evk.
