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 0e03b8fd2936 ("crypto: xilinx - Turn SHA into a tristate and allow COMPILE_TEST") but not Fixes: that commit.
