-Subject: dmar: fix using early fixmap mapping for DMAR table parsing
-References: fate #303948 and fate #303984
-Patch-Mainline: queued for .28

-Very early detection of the DMAR tables will setup fixmap mapping. For
-parsing these tables later (while enabling dma and/or interrupt remapping),
-early fixmap mapping shouldn't be used. Fix it by calling table detection
-routines again, which will call generic apci_get_table() for setting up
-the correct mapping.
