PCI: brcmstb: Set MLW based on "num-lanes" DT property if present

Browse source

By default, the driver relies on the default hardware defined value for the
Max Link Width (MLW) capability. But if the "num-lanes" DT property is
present, assume that the chip's default capability information is incorrect
or undesired, and use the specified value instead.
