[Shubhrajyoti D]

The patch series does the following

- Warn fixes if CONFIG_PM_RUNTIME is not selected.
- I2C register restore only if context if the context is lost
- Bus busy recovery mechanism.
- the reset is not done in init.

v2 changes
-Adds a patch to use devm_* functions
-Also checks the return type of the get_sync and in case
 of errors prevents register access.
- In case of i2c remove register access was done without any
 get_sync fix the same.
- Adds a pdata function pointer to do context save restore

v3 changes
- Split the omap_i2c_isr to increase readability
- Adds the restore flag patch for OMAP4 to the series
- Make the i2c use SET_RUNTIME_PM_OPS
v4 changes
- Folds a patch from Tasslehoff to prevent any merge conflicts.
- Prevents the XDUF flag to be set if the underflow condition is not met.

Tested on omap4sdp and omap3sdp.
