iio: adc: ade9000: request interrupts after powering the device

Browse source

The IRQ handlers do SPI register accesses, but the interrupts were
requested before the vdd regulator was enabled. An interrupt arriving
while the chip is unpowered runs a handler against a dead chip, causing
SPI errors or garbage reads.

Request the interrupts after enabling the regulator. This keeps irq1
registered before ade9000_reset(), which waits on it, and lets devm free
the interrupts before the regulator is disabled.
