ARM: 9306/1: cacheflush: avoid __flush_anon_page() missing-prototype warning
The prototype for __flush_anon_page() is intentionally hidden
inside the flush_anon_page() inline function to prevent it from
being called from drivers.
When building with 'W=1', this causes a warning:
arch/arm/mm/flush.c:358:6: error: no previous prototype for '__flush_anon_page' [-Werror=missing-prototypes]
Work around this by adding a prototype directly next to the function
definition.
