Subject: [PATCH 5.4 262/314] usb/ehci-platform: Set PM runtime as active on resume

From: Qais Yousef <qais.yousef@....com>

[ Upstream commit 16bdc04cc98ab0c74392ceef2475ecc5e73fcf49 ]

Follow suit of ohci-platform.c and perform pm_runtime_set_active() on
resume.

ohci-platform.c had a warning reported due to the missing
pm_runtime_set_active() [1].
