- Update PORT_LOGIC_LTSSM_STATE_MASK to be a 6-bit mask as per spec, not a
  5-bit mask (Shawn Lin)

- Clear L1 PM Substate Capability 'Supported' bits unless glue driver says
  it's supported, which prevents users from enabling non-working L1SS.
  Currently only qcom and tegra194 support L1SS (Bjorn Helgaas)

- Remove now-superfluous L1SS disable code from tegra194 (Bjorn Helgaas)

- Configure L1SS support in dw-rockchip when DT says 'supports-clkreq'
