So now we may detect MMC/SD-card existence and
instead of completely misleading message on missing card:
------------------------>8-----------------------
Loading Environment from FAT... Card did not respond to voltage select!
------------------------>8-----------------------
we now get very clear one:
------------------------>8-----------------------
Loading Environment from FAT... MMC: no card present
------------------------>8-----------------------

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.

In axs103 v1.1 procedure to kick-start slave cores has changed quite a bit
compared t previous implementation.
In particular:
* We used to have a generic START bit for all cores selected by CORE_SEL
mask. But now we don't touch CORE_SEL at all because we have a dedicated
START bit for each core:
bit 0: Core 0 (master)
bit 1: Core 1 (slave)
* Now there's no need to select "manual" mode of core start
Additional challenge for us is how to tell which axs103 firmware we're
dealing with. For now we'll rely on ARC core version which was bumped
from 2.1c to 3.0.

* Rely on default pulse polarity value
* Don't mess with "multicore" value as it doesn't affect execution
In essence we now do a bare minimal stuff:
1) Select HS38x2_1 with CORE_SEL=1 bits
2) Select "manual" core start (via CREG) with START_MODE=0
3) Generate cpu_start pulse with START=1

As of now we have 2 flavors of ARC SDP boards:
1) AXS101 - with ARC770 in ASIC
2) AXS103 - with ARC HS38 in FPGA
Both options share exactly the same base-board and only differ with
CPU-tiles in use. That means all peripherals are the same (they are
implemented in FPGA on the base-board) and so generic board could be
used for both.
While at it:
* Recreated defconfigs with savedefconfig
* In include/configs/axs10x.h numerical sizes replaced with
defines from linux/sizes.h for better readability.
