It seems to me that clock rate is set properly. It's even better than before
since there is no error between wanted and real clock. I bet that if you call
clk_get_rate() directly behind clk_set_rate() in mmc driver, you'll get
correct value.
However, it seems that at some point some other peripheral changes it's parent
clock rate, which inadvertely changes emmc2 clock rate too. The only possible
clock which could interfere is sata. Can you disable driver in you kernel
config and try again?
