We are currently having the exact same discussion problem on the altera
version of dw_mmc: It seems that all this driver does in addition to the
common code is to have a custom way to set up the card clocks.

In both cases, there is a custom piece of IP logic providing this clock
(here it is in the "hisilicon,pctrl" node). IMHO that should be a proper
clock driver so you can use the existing call to clk_set_rate to set
it up and not need a special platform driver at all.
