[PATCH] gpio: bd7xxxx: use helper variable for pdev->dev

[PATCH] gpio: bd7xxxx: use helper variable for pdev->dev

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

Using a helper local variable to store the address of &pdev->dev adds
to readability and allows us to avoid unnecessary line breaks.
