Separate the D3 delay increase functionality out of quirk_radeon_pm() into its own function so that it can be shared with other quirks, including the AMD Ryzen XHCI quirk that will be introduced in a followup commit. Tweak the function name and message to indicate more clearly that the delay relates to a D3hot-to-D0 transition.
