sparc: cacheflush_32.h needs struct page

Browse Source 
Add a struct page forward declaration to cacheflush_32.h.
Fixes this build warning:

    CC      drivers/crypto/xilinx/zynqmp-sha.o
  In file included from arch/sparc/include/asm/cacheflush.h:11,
                   from include/linux/cacheflush.h:5,
                   from drivers/crypto/xilinx/zynqmp-sha.c:6:
  arch/sparc/include/asm/cacheflush_32.h:38:37: warning: 'struct page' declared inside parameter list will not be visible outside of this definition or declaration
     38 | void sparc_flush_page_to_ram(struct page *page);

Exposed by commit 0e03b8fd29 ("crypto: xilinx - Turn SHA into a
tristate and allow COMPILE_TEST") but not Fixes: that commit because the
underlying problem is older.
