riscv/mb/qemu: fix DRAM probing
Current version of qemu raise an exception when accessing invalid
memory. Modify the probing code to temporary redirect the exception
handler like on ARM platform.
Also move saving of the stack frame out to trap_util.S to have all at
the same place for a future rewrite.
TEST=boots to ramstage
