drivers: i2c: Add SAM0 I2C driver This adds a SERCOM I2C driver for SAM0 series chips. Tested with a SAMD21 chip on a SSD1306 display and a MLX90393 sensor. Only compile tested for SAMD20 and SAMR21. Signed-off-by: Derek Hageman <hageman@inthat.cloud>

drivers: i2c: Update drivers to use devicetree Kconfig symbol Update i2c drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>

select DMA
help
This enables DMA driven transactions for the I2C peripheral.
DMA driven mode requires fewer interrupts to handle the
transaction and ensures that high speed modes are not delayed
by data reloading.
