From: Kai-Heng Feng <kai.heng.feng@canonical.com>

commit b63e48fb50e1ca71db301ca9082befa6f16c55c4 upstream.

Realtek Hub (0bda:0x0487) used in Dell Dock WD19 sometimes drops off the
bus when bringing underlying ports from U3 to U0.

Disabling LPM on the hub during setting link state is not enough, so
let's disable LPM completely for this hub.
