Subject: [PATCH v4 04/10] PCI: qcom-ep: Drop 'Link is enabled' from the
 debug message for BME event

Bus Master Enable (BME) event that is generated by the Qcom PCIe EP
controller due to host setting the Bus Master Enable bit in the Command
register doesn't have anything to do with the PCIe link.

Hence, drop the bogus statement.
