csky: add arch support current_stack_pointer

To follow the existing per-arch conventions, using "current_stack_pointer"
to set sp.

This will let it be used in non-arch places(like HARDENED_USERCOPY).

Refer to the implementation of riscv commit fdecfea09328 ("riscv: Rename
"sp_in_global" to "current_stack_pointer"").
