i2c: designware: Add disabling clocks when probe fails

Browse Source 
[ Upstream commit c149841b069ccc6e480b00e11f35a57b5d88c7bb ]

After an error occurs during probing state, dw_i2c_plat_pm_cleanup() is
called. However, this function doesn't disable clocks and the clock-enable
count keeps increasing. Should disable these clocks explicitly.
