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
- pwr_key=y

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 Board init
led_setup code.

In case of a power interruption, human intervention is required which
is not desirable if the device is installed at a remote location. Drop
yellow LED as it is not much of use. Keep red LED(diy-led) as it is, to
indicate board in full power mode.

Added support for onboard LED's and push button. When powered board will be
in low power mode(yellow LED), on button press, board enters full power mode
(red LED) and boots u-boot.

roc-pc-rk3399 board has one user button & three user LED's. Currently
we don't have any code support for these devices. Since button and LED's are
specific to roc-pc-rk3399 board, split it into its own board file and add code
support here.
