Change subject: WIP: riscv/mb/qemu: fix DRAM probing
......................................................................

Patch Set 2:

We do not need to scan when using qemu.  The ddr size is known and can be a fixed value.

See
https://review.coreboot.org/c/coreboot/+/38904

This makes much more sense to have an option to compile coreboot for qemu-riscv with
the value you want to use then specify this (or a smaller value) on the cmdline. 
No need to muck with exception handlers, etc..
