Subject: [PATCH] scsi: ufs: Move UFS trace events to private header

ufs trace events are called exclusively from the ufs core drivers.  Make
those events privet to the core driver.

The MAINTAINERS file does not need updating as the maintainership
remains the same and the relevant directory is already covered.
