[U-Boot] [U-Boot, v5, 14/18] rockchip: back-to-bootrom: replace assembly-implementation with C-code

[Philipp Tomsich]

> The back-to-bootrom implementation for Rockchip has always relied on
> the stack-pointer being valid on entry, so there was little reason to
> have this as an assembly implementation.
> 
> This provides a new C-only implementation of save_boot_params and
> back_to_bootrom (relying on setjmp/longjmp) and removes the older
> assembly-only implementation.
