drivers/iio/adc/at91_adc.c: use devm_ functions
The various devm_ functions allocate memory that is released when a driver
detaches. This patch uses these functions for data that is allocated in
the probe function of a platform device and is only freed in the remove
function.
The call to platform_get_resource(pdev, IORESOURCE_MEM, 0) is moved coser
to the call to devm_request_and_ioremap, which is th first use of the
result of platform_get_resource.
This does not use devm_request_irq to ensure that free_irq is executed
before its idev argument is freed.
