RISC-V: Mark ROM read-only after copying in code

The sifive_u machine already marks its ROM readonly however
it has the wrong base address for its mask ROM. This patch
fixes the sifive_u mask ROM base address.

This commit makes all other boards consistently use mask_rom
as the variable name for their ROMs. Boards that use device
tree now check that that the device tree fits in the assigned
ROM space using the new qemu_fdt_totalsize(void *fdt)
interface, adding a bounds check and error message. This
can detect truncation.
