drivers: adc: Add ADC xmc4xxx drivers
The ADC module has four conversion groups, each one is set up as a zephyr device. The start-up calibration is initiated globally for all groups and it is run in each device init function. The ADC module supports post calibration per group. Post calibration is run automatically after each group acquires the samples. Signed-off-by: Andriy Gelman <andriy.gelman@gmail.com>
