Subject: [PATCH 5.4 260/314] usb/xhci-plat: Set PM runtime as active on resume

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

[ Upstream commit 79112cc3c29f4a8c73a21428fbcbcb0afb005e3e ]

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].
