doc: rockchip: Add global doc for rk3399 build/flash

Since rockchip have an individual doc/README.rockchip, it would
be better to update the same instead of maintaining it separately
in board files.

So, add the documentation for rk3399
- procedure to build for Rockchip miniloader and
  U-Boot SPL options
- procedure to boot from SD for Rockchip miniloader and
  U-Boot SPL options
- procedure to build ATF, PMU M0 firmware for puma boards
- add boot logs of each option, so-that it would help for future
  boards porting
