[PATCH v3 1/5] rk3399: spl: Add rk_spl_board_init as __weak

[Jagan Teki <jagan@amarulasolutions.com>]

Current spl_board_init is mostly specific to puma-rk3399
target and in other words it cannot be required or useful
for other rk3399 boards.

Some boards require their custom initialization to be part
of spl_board_init like roc-rk3399-pc require leds setup,
environments.

So, this patch handles all these possible scenarios.
Add rk_spl_board_init as __weak so that boards that require
their own custom initialization can be defined on their
board file.
