Subject: [PATCH] sparc32, leon: APBUART driver must use archdata to get IRQ
number
See Commit id 1636f8ac2b08410df4766449f7c86b912443cd99 (sparc/of:
Move of_device fields into struct pdev_archdata), this patch
is similar to 19e4875fb21a69fbf620e84769a74d189c69c58d (of/sparc:
fix build regression from of_device changes)
