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.

Usually printing the SPL banner varies between architecture
or board codes.
- Some would print before relocation at the end 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 happens properly since it prints all after that.
- Some would print after relocation at the spl_board_init for
? making sure all initialization prior to relocation would
happen properly. Also debug uart on these cases would be
available before relocation. So debug support is available
in before and after relocation.
Rockchip SPL is following formar step to print the banner at
the end of board_init_f.
To support various custom use cases in SPL like leds, environment,
board detections later options like printing the banner after
relocation would be a better option. Printing banner would also
help to support debugging availability between relocation codes,
like debug uart available before relocation and banner availability
after relation.
By demonstrating all the above use cases, this patch is trying
to print the SPL banner after relocation.

roc-rk3399-pc has some specific requirements to support LEDS,
environment. board detection and etc prior to U-Boot proper.
So as of now SPL would be a better stage for these custom board
requirements to support unlike TPL. Adding few of these custom
requirements like LEDS in TPL would require extra code pulling
and also the size of TPL can grow.
So, this patch moves the leds code from TPL into SPL after relocation.

reset cause is a generic functionality based on the soc
cru registers in rockchip. This can be used for printing
the cause of reset in cpuinfo or some other place where
reset cause is needed.?
Other than cpuinfo, reset cause can also be using during
bootcount for checking the specific reset cause and glow
the led based on the reset cause.
So, let's separate the reset cause code from cpuinfo, and
add a check to build it for rk3399, rk3288 since these two
soc are supporting reset cause as of now.

ROC-RK3399-PC has specific set of configurations for
on-board led setup.
Due to easiness for user to know the state of the board
roc-rk339-pc board code will setup the low power led
on/off, and waiting for user to press power key and then
glow full power led.
All this needs to happen only during power-on-reset not
for soft reset or WDT.
Also, it is not a proper usage to ask the user to press
the Power key if the board connected remotely, so add
the environment variable 'pwr_key' to check as well.
So, user need to press Power key only
- during POR
