arc: cache - build invalidate_icache_all() and invalidate_dcache_all()
always Make both invalidate_icache_all() and invalidate_dcache_all() available even if U-Boot is configured with CONFIG_SYS_DCACHE_OFF and/or CONFIG_SYS_ICACHE_OFF. This is useful because configuration of U-Boot may not match actual hardware features. Real board may have cache(s) but for some reason we may want to run U-Boot with cache(s) disabled (for example if some peripherals work improperly with existing drivers if data cache is enabled). So board may start with cache(s) enabled (that's the case for ARC cores with built-in caches) but early in U-Boot we disable cache(s) and make sure all contents of data cache gets flushed in RAM.
