Subject: [PATCH 06/10] sparc64: Fix prototype warning for dma_4v_iotsb_bind

From: Sam Ravnborg <sam@...nborg.org>

Fix the following warning:
sparc/kernel/pci_sun4v.c:259:15: warning: no previous prototype for ‘dma_4v_iotsb_bind’

The function dma_4v_iotsb_bind is not used outside the file, so declare
it static.
