[PATCH v9 0/2] Basic early_printk and smoke test implementation



The patch series introduces the following:
- the minimal set of headers and changes inside them.
- SBI (RISC-V Supervisor Binary Interface) things necessary for basic
  early_printk implementation.
- things needed to set up the stack.
- early_printk() function to print only strings.
- RISC-V smoke test which checks if  "Hello from C env" message is
  present in serial.tmp

The patch series is rebased on top of the patch "include/types: move
stddef.h-kind types to common header" [1]
