exynos: config: enable arch memcpy and arch memset
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
