[PATCH] iio: adc: bcm_iproc_adc: Use dev_err_probe() for resource acquisition failures

[mdshahid03 at gmail.com]

From: Mohammad Shahid <mdshahid03 at gmail.com>

Replace open-coded dev_err() and error returns with dev_err_probe()
for failures from syscon_regmap_lookup_by_phandle() and devm_clk_get()
in the probe path.

This simplifies error handling and properly handles deferred probing.
