Re: [U-Boot] [U-Boot, v3, 3/4] ARM: cache: implement a default weak flush_cache() function

Current many cpu use the same flush_cache() function, which just call the flush_dcache_range(). So implement a weak flush_cache() for all the cpus to use.

In original weak flush_cache() in arch/arm/lib/cache.c, there has some code for ARM1136 & ARM926ejs. But in the arch/arm/cpu/arm1136/cpu.c and arch/arm/cpu/arm926ejs/cache.c, there implements a real flush_cache() function as well. That means the original code for ARM1136 & ARM926ejs in weak flush_cache() of arch/arm/lib/cache.c is totally useless.

So in this patch remove such code in flush_cache() and only call flush_dcache_range().

Applied to u-boot/master, thanks!
