Commit 7ef9651e9792 ("clk: Provide new devm_clk helpers for prepared
and enabled clocks") provides a new helper function to prepare and
enable a clock which keeps prepared (or enabled) during the whole
lifetime of the driver.

Use devm_request_irq() to request the interrupt, so we can
avoid having to manually clean this up.

Use the dev_err_probe() helper to simplify error handling during probe.
This also handle scenario, when EDEFER is returned and useless
error is printed.

Changes in v2:
- Also use devm_request_irq() and dev_err_probe() to clean up the at91_adc.
- Split the at91_adc patch out to be a new patch set.

iio: adc: at91_adc: Use devm_clk_get_enabled() helper function
iio: adc: at91_adc: Use devm_request_irq() helper function
iio: adc: at91_adc: Simplify with dev_err_probe()
