[Oleksii Kurochko <oleksii.kurochko@gmail.com>]

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

Changes in V2:
    - update commit patches commit messages according to the mailing
      list comments
    - Remove unneeded types in <asm/types.h>
    - Introduce definition of STACK_SIZE
    - order the files alphabetically in Makefile
    - Add license to early_printk.c
    - Add RISCV_32 dependecy to config EARLY_PRINTK in Kconfig.debug
    - Move dockerfile changes to separate config and sent them as
      separate patch to mailing list.
    - Update test.yaml to wire up smoke test
