The commit introduced regression for hsdk4xd platform.
The hsdk4xd SoC setup from soc_early_asm_init_percpu need to be done
in early code before any C code execution.
The current approach has multiple issues
- we call function (which can be easily implemented in C for
this or other SoC) from the place where we haven't setup stack
pointer (so we can't use stack) - which is very error-prone
- we never return back from soc_reset_hook on hsdk4xd platform
So let's just revert it for now. If any other ARC SoC need to use
soc_reset_hook - than it can be implemented properly.
This reverts commit 8c32a82e47.
