[PATCH v4 2/3] iio: adc: bcm_iproc_adc: Introduce local device pointer

[mdshahid03@gmail.com]

From: Mohammad Shahid <mdshahid03@gmail.com>

Introduce a local 'struct device *dev' variable in iproc_adc_probe()
and use it instead of repeatedly referencing '&pdev->dev'.

This simplifies the code and makes subsequent error handling changes
less verbose.

No functional change intended.
