[PATCH 3/4] power: supply: axp20x_usb: Introduce a helper variable for &pdev->dev

["Uwe Kleine-König" <ukleinek@debian.org>]

With the next commit adding several new usages of &pdev->dev, a helper
variable is well justified. To not clutter that commit, split out the
introduction of the helper out in this separate change to simplify
review.
