Revert "fs: fat: assign rootdir sector when accessing root directory"

This particular commit is causing a regression on stih410-b2260 and
other platforms when reading from FAT16. Noting that I had rebased the
original fix from Thomas onto then-current master, there is also
question from Akashi-san if the change is still needed after other FAT
fixes that have gone in.

This reverts commit a68b0e11ea774492713a65d9fd5bb525fcaefff3.

fs: check FAT cluster size

The cluster size specifies how many sectors make up a cluster. A
cluster size of zero makes no sense, as it would mean that the
cluster is made up of no sectors. This will later lead into a
division by zero in sect_to_clust(), so better take care of that
early.

The MAX_CLUSTSIZE define can reduced using a define to make some
room in low-memory system. Unfortunately if the code reads a
filesystem with a bigger cluster size it will overflow the buffer.

Patch queue for efi - 2018-09-26

A lot of goodness in this release. We're *very* close to running the
UEFI Shell and SCT natively. The only missing piece are HII protocols.

- FAT write support (needed for SCT)
- improved FAT directory support (needed for SCT)
- RTC support with QEMU -M virt
- Sandbox support (run UEFI binaries in Linux - yay)
- Proper UTF-16 support
- EFI_UNICODE_COLLATION_PROTOCOL support (for UEFI Shell)
- EFI_SIMPLE_TEXT_INPUT_EX_PROTOCOL support (for UEFI Shell)
- Fix window size determination
- Fix Tegra by explicitly unmapping RAM
- Clean up handle entanglement
- Lots of generic code cleanup

fs: fat: support write with sub-directory path

In this patch, write implementation is overhauled and rewritten by
making full use of directory iterator. The obvious bonus is that we are
now able to write to a file with a directory path, like /A/B/C/FILE.

Please note that, as there is no notion of "current directory" on u-boot,
a file name specified must contain an absolute directory path. Otherwise,
"/" (root directory) is assumed.

fs: fat: assure iterator's ->dent belongs to ->clust

In my attempt to re-work write operation, it was revealed that iterator's
"clust" does not always point to a cluster to which a current directory
entry ("dent") belongs.
This patch assures that it is always true by adding "next_clust" which is
used solely for dereferencing a cluster chain.

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.

After those changes the buffers are properly aligned (with both start
