dt-bindings: PCI: brcmstb: Add property "brcm,clkreq-mode"

Browse source

The Broadcom STB/CM PCIe HW -- a core that is also used by RPi SOCs --
requires the driver to deliberately place the RC HW one of three CLKREQ#
modes.  The "brcm,clkreq-mode" property allows the user to override the
default setting.  If this property is omitted, the default mode shall be
"default".
