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.

The QSPI module on i.MX7D is modified from i.MX6SX. The module used on
i.MX6UL/6ULL is reused from i.MX7D. They share same tx buffer size.

The endianness is not set at qspi driver initialization. So if we don't
boot from QSPI, we will get wrong endianness when accessing from AHB
address directly.

Add the compatible entry for 6ul/7d.

In some of the QSPI controller version, there must be atleast

error bit will be set. The code will not make any behavior change
for previous controller as the transfer data size in ipcr register
is still the same.
