tools: stop supporting builtin springboard

[ampresent]

Once we have some kernels customized for plugsched. And we patched these kernels with builtin springboards. Now that dynamic springboard is mature enough, and doesn't require any customizing to the kernel, we can delete the support for builtin springboard.

Also, this patch fixes the bug, that plugsched fails to work on some of these kernels. Because currently, dynamic_springboard.patch is composed of stack-pivot and springboard. And for these kernels, stack-pivot is not applied as well. Without stack-pivot, the scheduler is easily broken.
