This patch adds part_get_info_by_dev_and_name_or_num() function which
allows us to get partition info from its number or name. Partition of
interest is specified by string like "device_num:partition_number" or
"device_num#partition_name".

The patch was extracted from [1].

blk_get_device_by_str was skipping part_init when hw partition 0 was
selected because it is the default. However, this caused issues when
switching to a non-zero partition and then back to partition zero, as
stale data from the wrong partition was returned.

Remove this optimization and call part_init regardless of the selected
partition.

Use '>> 11' instead of '/ 2048' to avoid the division.

Underlying API should already print some meaningful error message, so
this one is just brings more noise. E.g. we can see log like this:

    MMC: no card present
    ** Bad device mmc 0 **

Obviously, second error message is unwanted. Let's only print it in case
when DEBUG is defined to keep log short and clear.

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.

We have a large number of places where while we historically referenced
gd in the code we no longer do, as well as cases where the code added
that line "just in case" during development and never dropped it.
