Subject: [PATCHv3 06/16] OMAP: I2C: Fix the mismatch of pm_runtime enable and disable

Currently the i2c driver calls the pm_runtime_enable and never
the disable. This may cause a warning when pm_runtime_enable
checks for the count match.Attempting to fix the same by calling
pm_runtime_disable in the error and the remove path.
