usb: xhci-mtk: correct most kernel-doc problems in xhci-mtk.h

Correct the kernel-doc notation in xhck-mtk.h to avoid most kernel-doc
warnings. Summary of changes:

- don't use /** to begin comments that are not in kernel-doc format
- add missing "struct mu3h_sch_tt" kernel-doc line
- convert several "struct mu3h_...:" to using " - " to separate the
  struct name from its short description
- add a missing @speed: struct member description

Warning messages that are fixed:

xhci-mtk.h:25: warning: This comment starts with '/**', but isn't a
 kernel-doc comment. Refer Documentation/doc-guide/kernel-doc.rst
