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.

The new common rockchip pinctrl driver does not support explicit
requests for a particular pinctrl function.  As a result, the
board_init() function bails out early before enabling the boot-on
regulators.  Fix this by simply removing the request for pwm0, pwm2
and pwm3.  The generic DM code already does the necessary
configuration if necessary.

Support common spl_board_init by moving code from puma
board file into, common rk3399-board-spl.c.

Part of the code has sysreset-gpio, regulators_enable_boot_on
but right now only puma board is using this with relevant
config options rest remains common for all targets.

preloader_console_init is used for printing SPL boot banner that
usually called from spl_board_init.

The current spl_board_init in evb and rock960 is enabling explicit
pinctrl, debug uart prior to calling preloader_console_init which
eventually not required since board_init_f is already enabled
debug uart.

So, drop those explicit enablement calls from  spl_board_init of
evb, rock960.

Tested this by enabling CONFIG_SPL_BOARD_INIT and adding
u-boot,dm-pre-reloc property for uart node.

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

The later-stage spl_board_init (as opposed to board_init_f) should set
up board-specific details: these differ between the EVB-RK3399 and the
RK3399-Q7 (Puma).

This moves spl_board_init back into the individual boards and removes
the unneeded functionality from Puma.
