riscv: Allow device trees to be built into the kernel Some systems don't provide a useful device tree to the kernel on boot. Chasing around bootloaders for these systems is a headache, so instead le't's just keep a device tree table in the kernel, keyed by the SOC's unique identifier, that contains the relevant DTB. This is only implemented for M mode right now. While we could implement this via the SBI calls that allow access to these identifiers, we don't have any systems that need this right now.

riscv: move errata/ and kvm/ builds to arch/riscv/Kbuild Commit 909548d6c578 ("riscv: add arch/riscv/Kbuild") intended that subdirectories in arch/riscv/ would be added in arch/riscv/Kbuild.

kbuild: use more subdir- for visiting subdirectories while cleaning Documentation/kbuild/makefiles.rst suggests to use "archclean" for cleaning arch/$(SRCARCH)/boot/, but it is not a hard requirement. Since commit d92cc4d51643 ("kbuild: require all architectures to have arch/$(SRCARCH)/Kbuild"), we can use the "subdir- += boot" trick for all architectures. This can take advantage of the parallel option (-j) for "make clean". I also cleaned up the comments in arch/$(SRCARCH)/Makefile. The "archdep" target no longer exists.

RISC-V: Add purgatory This patch adds purgatory, the name and concept have been taken from kexec-tools. Purgatory runs between two kernels, and do verify sha256 hash to ensure the kernel to jump to is fine and has not been corrupted after loading. Makefile is modified based on x86 platform.
