IIO: ti_adc: Enabling of IRQ for continuous mode
Since IRQ is a part of continuous mode feature, Enabling should also take place when continuous data is asked for. In default mode ADC is configured as one shot, IRQ need not be enabled if one wants to use one shot mode only. Signed-off-by: Patil, Rachna <rachna@ti.com>
