[U-Boot] [PATCH] pci: gate print info of reading vender id with CONFIG_DM_PCI

[Gong Qianyu]

From: Mingkai Hu <Mingkai.Hu at freescale.com>

Referring to 'commit ff3e077bd23c ("dm: pci: Add a uclass for PCI")'.

For legacy PCIe driver, it needs loop to read the vender_id from
devie 0 to devie 255 to check if there is device available.
Reading non-existen device will trigger the "Cannot read bus
configuration: -1" information.
