[PATCH] staging: mt7621-pci-phy: Use devm_platform_ioremap_resource() in mt7621_pci_phy_probe()

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 18 Sep 2019 21:01:32 +0200

Simplify this function implementation by using a known wrapper function.

This issue was detected by using the Coccinelle software.
