The probe function adds the MMC host which can start accepting request

immediatly, but it's not always the case. This assumption can causes
a BUG() when the clocks are disabled. The fix is to just remove the
clock disable in the probe function.

I can add acked-by and/or tested-by if needed.

Nack from me. The fix is incorrect. The clocks are alread refcounted in the clock driver. There should be no need to "leave it on because someone else might access it". Every code that needs the clock should have a clk_enable/disable around it and it would all work fine.
