The RISC-V and AArch64 bare-metal kernel images share a common header format, and require essentially the same execution environment: loaded close to the start of RAM, entered with paging disabled, and passed a pointer to a flattened device tree that describes the hardware and any boot arguments. Implement basic support for executing bare-metal RISC-V and AArch64 kernel images. The (trivial) AArch64-specific code path is untested since we do not yet have the ability to build for any bare-metal AArch64 platforms. Constructing and passing an initramfs image is not yet supported. Rename the IMAGE_BZIMAGE build configuration option to IMAGE_LKRN, since "bzImage" is specific to x86. To retain backwards compatibility with existing local build configurations, we leave IMAGE_BZIMAGE as the enabled option in config/default/pcbios.h and treat IMAGE_LKRN as a synonym for IMAGE_BZIMAGE when building for x86 BIOS.
