Subject: [PATCH] vfio/pci: demote hiding ecap messages to debug level

Seeing a burst of messages like this:

    vfio-pci 0000:98:00.0: vfio_ecap_init: hiding ecap 0x19@...d0
    vfio-pci 0000:98:00.0: vfio_ecap_init: hiding ecap 0x25@...00
    vfio-pci 0000:98:00.0: vfio_ecap_init: hiding ecap 0x26@...10
    vfio-pci 0000:98:00.0: vfio_ecap_init: hiding ecap 0x27@...50
    vfio-pci 0000:98:00.1: vfio_ecap_init: hiding ecap 0x25@...00
    vfio-pci 0000:b1:00.0: vfio_ecap_init: hiding ecap 0x19@...d0
    vfio-pci 0000:b1:00.0: vfio_ecap_init: hiding ecap 0x25@...00
    vfio-pci 0000:b1:00.0: vfio_ecap_init: hiding ecap 0x26@...10
    vfio-pci 0000:b1:00.0: vfio_ecap_init: hiding ecap 0x27@...50
    vfio-pci 0000:b1:00.1: vfio_ecap_init: hiding ecap 0x25@...00

is of little to no value for an ordinary user.

Hence, use pci_dbg() instead of pci_info().
