-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
