Alexander von Gluck IV 38f17b01ce radeon_hd: Polaris10 power distribution fix
* Helps prevent mainboard explosions and other bad stuff.
* ...maybe not explosions, but bad things.
* The RX 480 reference design can pull as much as 90W
  from its PCIe slot at load. PCIe is rated for 75W.
* This change overloads the PCIe power cables vs the PCIe
  slot. The PCIe power cables can handle going over spec.
* Untested since we really can't come close to loading a
  RX 480 without hardware OpenGL ^_^
* Should be able to test on real hardware within a week.
