Subject: [PATCH 08/32] drm/i915: i915_gem_ttm_pm.c: fix kernel-doc markups

The documentation for the flags field is missing there. It sounds
that some last-time change converted some bools into flags, but
the kernel-doc change didn't follow it.

Fix those warnings:

	drivers/gpu/drm/i915/gem/i915_gem_ttm_pm.c:135: warning: Function parameter or member 'flags' not described in 'i915_ttm_backup_region'
	drivers/gpu/drm/i915/gem/i915_gem_ttm_pm.c:135: warning: Excess function parameter 'allow_gpu' description in 'i915_ttm_backup_region'
	drivers/gpu/drm/i915/gem/i915_gem_ttm_pm.c:135: warning: Excess function parameter 'backup_pinned' description in 'i915_ttm_backup_region'
	drivers/gpu/drm/i915/gem/i915_gem_ttm_pm.c:199: warning: Function parameter or member 'flags' not described in 'i915_ttm_restore_region'
	drivers/gpu/drm/i915/gem/i915_gem_ttm_pm.c:199: warning: Excess function parameter 'allow_gpu' description in 'i915_ttm_restore_region'
