Subject: [PATCH v3 1/2] drm/modes: parse_cmdline: Make mode->*specified handling more uniform

The various mode->*specified flags are not handled in an uniform way:
some flags are set by the corresponding drm_mode_parse_cmdline_*()
function, some flags by the caller of the function, and some flags by
both.

Make this uniform by making this the responsibility of the various
parsing helpers, i.e.
  - Move the setting of mode->specified from caller to callee,
  - Drop the duplicate setting of mode->bpp_specified and
    mode->refresh_specified from callers.
