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.

The SDcard initialization procedure does a few more things than it did earlier:
* switch the bus width even for 1-bit bus width
* check that speed has been properly set (in resp[4] of SD_CMD_SWITCH_FUNC)
Update the SD simulator to handle those requests gracefully.

These functions can be much simpler by squashing lines for immediate
return.
For *_bind() callbacks, they will be a simple wrapper function of an
upper-level bind API.
For mmc_set_{boot_bus_width,part_conf}, they will be a wrapper of
mmc_switch().

Update the sandbox MMC emulation to use driver model for MMC operations.

Add an emulation of an SD card to sandbox, allowing MMC to be used in tests.
The emulation is very simple, supporting only card detection and reading
test data.

Add a test to confirm that we can probe this device. Since there is no
MMC stack support in sandbox at present, this is as far as the test goes.
