[PATCH] drm/xe: Fix arg to pci_iomap()

[Lucas De Marchi <lucas.demarchi@intel.com>]

Commit 2d8865b27724 ("drm/xe: Move BAR definitions to dedicated file")
moved the BAR definition to the header, but replaced the wrong arg in
the pci_iomap() function - the last arg is actuall the length, not the
BAR. Luckily GTTMMADR_BAR == 0, so it still works. Fix the argument
to avoid confusion.
