[PATCH 4/5] rockchip: tpl: Print TPL banner at end-of board_init_f

[Jagan Teki <jagan@amarulasolutions.com>]

Usually printing the TPL banner various between architecture
or board codes.
- Some of them would print at the end of board_init_f for
  making sure all initialization prior to this would happen
  properly. if at all there is a requirement for serial init,
  that happen properly since it prints all after that.
- Some of them would print at the beginning once the debug
  uart done. assuming this particular banner wouldn't require
  any serial setup code.

Rockchip TPL is following later one and printing early in
board_init_f.

But, sometimes there is a use case where we can print the banner
only when the board_init_early_f done.

It is  because board_init_early_f has gpio configuration required
for non-standard board design to glow the specific LEDs upon
user interaction. These board design wouldn't recommend to
print any console logs unless user interact with board via
some kind of power button.

This look specific to board but since all rockchip boards use
common tpl code, this seems to the desired solution. and also
it is following similar initialization as rockchip SPL like
- printing banner at end of board_init_f
- debug print at early board_init_f in debug_uart_init block.
