mci mxs: no need to call mxs_mci_setup_clock_speed in init ...

It will be called by set_ios anyway later. Also, do not
alter host->clock field, this is none of our business.

mci mxs: make the mci_host a member of mxs_mci_host ...

This allows for more type safety. passing a struct device_d
internally in the driver is not a good idea. Also, this
patch adds a void __iomem *regs to mxs_mci_host. dev->map_base
should not be used for register accesses.
