15f09a1a83 rockchip: use 'arch-rockchip' as header file path
Rockchip use 'arch-rockchip' instead of arch-$(SOC) as common
header file path, so that we can get the correct path directly.

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
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.

bc8e8fe40b rockchip: rk3399: Add missing sentinel in syscon
when enable PMIC rk808,the system will halt at very
 early stage,log is shown as bellow.

INFO:    plat_rockchip_pmu_init(1211): pd status 3e
INFO:    BL31: Initializing runtime services
INFO:    BL31: Preparing for EL3 exit to normal world
INFO:    Entry point address = 0x200000
INFO:    SPSR = 0x3c9
time 44561b, 0 (<<----Just stop here)

It's caused by the absence of "{ }" in syscon_rk3399.c
,which will lead to memory overflow like below.According
 to Sysmap file ,we can find the function buck_get_value
of rk808 is just follow the compatible struct,the pointer
"of_match" point to "buck_get_value",but it is not a
struct and don't have member of compatible, In this case,
system crash. So,on the face, it looks like that rk808 is
guilty.but he is really innocent.

while (of_match->compatible) { <<----------
    if (!strcmp(of_match->compatible, compat)) {
    *of_idp = of_match;
    return 0;
    }
    of_match++;
}
