[PATCH] PCI: fu740: do not use clock name when requesting clock

[Icenowy Zheng]

The DT binding of FU740 PCIe does not enforce a clock-names property,
and there exist some device tree that has a clock name that does not
stick to the one used by Linux DT (e.g. the one shipped with current
U-Boot mainline).

Drop the name in the clock request, instead just pass NULL (because
this device should have only a single clock).
