arm: mvebu: theadorable: Add board-specific PEX detection pulse width
Define a board-specific detection pulse-width array for the SerDes PCIe interfaces. If not defined in the board code, the default of currently 2 is used. Values from 0...3 are possible (2 bits). In this case of the theadorable board, PEX interface 0 needs a value of 0 for the detection pulse width so that the PCIe device (Atheros WLAN PCIe device) is consistantly detected.
