[U-Boot] Missing flush_cache in do_load function

[U-Boot] Missing flush_cache in do_load function

[Borsodi Petr]

Hi all,

I found a problem with load command on ARM based board. When I load hello_world standalone application using filesystem load command, the u-boot crashes. Loading with loads is OK.
I think that the problem is caused by cache inconsistency. If I add calling the flush_cache function, problem is solved.

I also ran into cache inconsistency problems when copying the stand 
alone from NOR flash to RAM. I was using Freescale 85xx SOC.

Based on a few email conversations I had at the time, I added

Maybe you will find something useful.
