phy: usb: phy-brcm-usb: Remove sysfs attributes upon driver removal

[ Upstream commit d9e100829fca6cbd270d7e005b0c0bb2d14924b8 ] 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.
