When calling dev_set_name() memory is allocated for the name for the
struct device.  Once that structure device is registered, or attempted
to be registerd, with the driver core, the driver core will handle
cleaning up that memory when the device is removed from the system.

Unfortunatly for the memstick code, there is an error path that causes
the struct device to never be registered, and so the memory allocated in
dev_set_name will be leaked.  Fix that leak by manually freeing it right
before the memory for the device is freed.

Currently .get_max_clock returns the current clock rate for cclk_emmc
on rk35xx, thus max clock gets set to whatever bootloader set it to.

In case of u-boot, it is intentionally reset to 50 MHz if it boots
from eMMC, see mmc_deinit() in u-boot sources. As a result, HS200 and
HS400 modes are never selected by Linux, because dwcmshc_rk35xx_postinit
clears appropriate caps if host->mmc->f_max is < 52MHz

cclk_emmc is not a fixed clock on rk35xx, so using
sdhci_pltfm_clk_get_max_clock is not appropriate here.

Implement rk35xx_get_max_clock that returns actual max clock for cclk_emmc.
