Subject: [PATCH] PCI: Reduce verbosity of device enable messages

Excessive logging of PCIe device enable operations can create significant
noise in system logs, especially in environments with a high number of
such devices, especially VFs.

High-rate logging can cause log files to rotate too quickly, losing
valuable information from other system components.This commit addresses
this issue by downgrading the logging level of "enabling device" messages
from `info` to `dbg`.
