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.

Now, arch/${ARCH}/include/asm/errno.h and include/linux/errno.h have
the same content. (both just wrap <asm-generic/errno.h>)
Replace all include directives for <asm/errno.h> with <linux/errno.h>.

When the original HBUS divider value is retrieved in mxs_ocotp_scale_hclk()
for the purpose or restoring it back later, the value is not shifted by the
HBUS divider offset in that register. This is not a problem, since the shift
is zero on all MXS hardware. Add the shift anyway, for completeness and in
case FSL ever decides to re-use this driver on future designs.

A previous operation may have set the error flag, which must be cleared
before a new write operation can be issued.

The write operation may fail when trying to write to a locked area. In
this case the ERROR bit is set in the CTRL register. Check for that
condition and return an error.

The code may goto 'fail' upon error with 'ret' variable set to an error
code, but this variable was being overwritten by a final preparation
function to restore the HCLK, so success was (in general) returned even
after an error was hit previously.
With this change, the function may now return success even if the final
preparation function fails, but it's probably enough to print a message
because (if successful) the real programming of the fuses has already
completed.

Add yet another OCOTP driver for this i.MX family. This time, it's a driver for
the OCOTP variant found in the i.MX23 and i.MX28. This version of OCOTP is too
different from the i.MX6 one that I could not use the mxc_ocotp.c driver without
making it into a big pile of #ifdef . This driver implements the regular fuse
command interface, but due to the IP blocks' limitation, we support only READ
and PROG functions.
