[PATCH v4 4/7] i915/gvt: remove spaces in pr_debug "gvt: core:" etc prefixes

[Jim Cromie <jim.cromie@gmail.com>]

Collapsing "gvt: core: " to "gvt:core: " is a better class-prefix;
dropping the internal spaces means a trailing space in a query will
more clearly terminate the prefix.

Consider a generic drm-debug example:

  # turn off most ATOMIC reports
  echo format "^drm:atomic: " -p > control

  # turn off all ATOMIC:* reports
  echo format "^drm:atomic:" -p > control

  # turn on ATOMIC:FAIL reports
  echo format "^drm:atomic:fail: " +p > control

Removing embedded spaces in the class-prefixes simplifies the
corresponding match-prefix.  This means that "quoted" match-prefixes
are only needed when the trailing space is desired, in order to
exclude explicitly sub-categorized pr-debugs; in this example,
"drm:atomic:fail:".

RFC: maybe the prefix catenation should paste in the " " class-prefix
terminator explicitly.  A pr_debug_() flavor could exclude the " ",
allowing ad-hoc sub-categorization by appending for example, "fail:"
to "drm:atomic:".
