PCI: dwc: Fix wrong PORT_LOGIC_LTSSM_STATE_MASK definition

[ Upstream commit bcc9a4a0bca3aee4303fa4a20302e57b24ac8f68 ]

As per DesignWare Cores PCI Express Controller Databook, section 5.50,
SII: Debug Signals, cxpl_debug_info[63:0]:

  [5:0] smlh_ltssm_state: LTSSM current state. Encoding is same as the
  dedicated smlh_ltssm_state output.

The mask should be 6 bits, from 0 to 5. Hence, fix the mask definition.
