riscv: kernel: Add support for hibernate/suspend to disk

The implementation assumes that exactly the same kernel is booted on the
same hardware.

We save the build number and date to the swap header so that we guarantee
not to resume with a different kernel upon booted up the hibernated image.

swsusp_arch_resume() and swsusp_arch_suspend() are coded as dummy
functions for now and shall complete in the subsequent patches.
