[U-Boot] [PATCH v5 1/7] exynos: config: enable arch memcpy and arch memset

[Lukasz Majewski <l.majewski@samsung.com>]

Hi Przemyslaw,

> This commit enables the following configs:
> - CONFIG_USE_ARCH_MEMCPY
> - CONFIG_USE_ARCH_MEMSET
> This increases the performance of memcpy/memset
> and also reduces the boot time.
> 
> This was tested on Trats2.
> A quick test with trace. Boot time from start to main_loop() entry:
> - ~1527ms - before this change (arch memset enabled for .bss clear)
> - ~1384ms - after this change
>
