[MXS MMC 4/5] Check the return codes of clk_enable() and mxs_reset_block()

Add an int return value to mxs_mmc_reset(), so that the return code of
mxs_reset_block() can be promoted to the caller.
Also check the return code of clk_enable() in the probe function.

Why __func__ here? dev_err and the msg itself should be indication enough?

Otherwise
