iio: adis: do not disabe IRQs in 'adis_init()'
With commitecb010d441
("iio: imu: adis: Refactor adis_initial_startup") we are doing a HW or SW reset to the device which means that we'll get the default state of the data ready pin (which is enabled). Hence there's no point in disabling the IRQ in the init function. Moreover, this function is intended to initialize internal data structures and not really do anything on the device. As a result of this, some devices were left with the data ready pin enabled after probe which was not the desired behavior. Thus, we move the call to 'adis_enable_irq()' to the initial startup function where it makes more sense for it to be. Note that for devices that cannot mask/unmask the pin, it makes no sense to call the function at this point since the IRQ should not have been yet requested. This will be improved in a follow up change. Fixes:ecb010d441
