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.

imx: mx27 move GPIO_PORTx to gpio.h

These GPIO_PORTx macros should be in gpio.h, but not in imx-regs.h.

Also, imx-regs.h and iomux-v3.h has same macro defintion for
GPIO_PORTx, and both of them are included in mxc_i2c.c(include
mxc_i2c.h). This will incur build warnings with macro redefinition.

Since iomux-v3.h is not compatible with mx27, we can not simply
include iomux-v3.h for mx27, so move the GPIO_PORTx to gpio.h to
fix the build warning.
