Subject: [PATCH 3/6] phy: usb: phy-brcm-usb: Remove sysfs attributes upon driver removal

From: Florian Fainelli <f.fainelli@...il.com>

We are not destroying the sysfs attribute groupe we registered during
the probe function which will make subsequent probe calls to that
driver fail. Correct that with adding a remove function which only
removes those attributes since the reference counting on clocks did its
job already.
