Due to the removal of weak functions in 7d6cee2cd0 ("cmd: cache: Remove weak function"), U-Boot fails to compile after updating to v2024.10 for mediatek target in OpenWrt with GCC-14 with error: cmd/cache.c: In function 'do_dcache': cmd/cache.c:57:25: error: implicit declaration of function 'noncached_set_region' [-Wimplicit-function-declaration]
Thus, provide a prototype in include/cpu_func.h to fix a build error in cmd/cache.c, since related prototypes are also located there.
The issue occured after the update of uboot-mediatek in OpenWrt to v2024.10, in combination with GCC-14 toolchain. It was reported and discussed in https://github.com/openwrt/openwrt/issues/16697, and temporarily fixed with https://github.com/openwrt/openwrt/commit/92ca322dd1f48158b8829fec59319a12e4....
