[U-Boot] [PATCH v2 7/8] trats2: defconfig: enable expert and skip memset at malloc init

Reduce the boot time of Trats2 by disabling the memset
at malloc init.

This was tested on Trats2.
A quick test with trace. Boot time from start to main_loop() entry:
- ~464ms - before this change (arch memset enabled for .bss clear)
- ~341ms - after this change
