m68k: sun3: Improve Sun3/3x DVMA abstraction in <asm/dvma.h>
When building with W=1:
arch/m68k/sun3/dvma.c:65:13: warning: no previous prototype for ‘sun3_dvma_init’ [-Wmissing-prototypes]
65 | void __init sun3_dvma_init(void)
| ^~~~~~~~~~~~~~
arch/m68k/sun3x/dvma.c:178:6: warning: no previous prototype for ‘dvma_unmap_iommu’ [-Wmissing-prototypes]
179 | void dvma_unmap_iommu(unsigned long baddr, int len)
| ^~~~~~~~~~~~~~~~
Fix this by moving the declarations for sun3_dvma_init() and
dvma_unmap_iommu() to <asm/dvma.h>. Avoid #ifdefs in callers by
providing dummy static inline functions.
