i2c: Move general configs to the top of Kconfig This patch moves the config options I2C_STATUS_DELAY, I2C_CLOCK_SPEED and I2C_DEBUG to the top of the Kconfig file. These options are independent of the device driver and should be placed together with option I2C_INIT_PRIORITY which is also independent.

i2c: restructure kconfig options () Moves config options for each controllers into their own Kconfig files. This keeps upper level Kconfig from getting too big. () Options for each controller are moved under their own submenus. () Adds the missing copyright to Kconfig.atmel_sam3.

i2c: Enable interrupts for QMSI shim driver Due to an issue with the interrupt-based transfer API from QMSI driver, the 'transfer' callback from the shim driver (i2c_qmsi_transfer) is implemented with polling APIs. This is not ideal because we are not able to sleep the current thread (so another task can be scheduled in) while the i2c operation is carried out. The interrupt issue with the QMSI driver has been solved then this patch fixes the shim driver so it uses the interrupt-based API and adds extra code to handle the thread synchronization. Finally, this patch also moves all 'struct device' related definitions from the bottom to the top of the i2c_qmsi.c file so the DEVICE_GET macro can be used in transfer_complete() and removes the init.h include since it is not needed anymore.
