scsi: ufs-qcom: expose debug registers by debugfs
Add support for exposing debug registers via debugfs. This
can be used for runtime debugging of failures/errors without
the need to add more prints to the console.
In order to avoid unnecessary code duplication, the function
for dumping registers to a file (in debugfs.c) has been
slightly modified and exposed as an external function.
