Subject: [PATCH] iio: adc: aspeed: propagate reset deassert errors

aspeed_adc_probe() continues to register ADC resources after deasserting the shared reset, even if the reset controller reports a failure.

A failed deassertion leaves the hardware unavailable, so stop probing before installing the cleanup action and enabling the ADC.
