Add defines for {in,out}s{b,w,l} functions to make asm-generic/io.h
aware of them.

Move this out of the common header and include it only where needed. In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly. Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

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.

Convert the nios2 architecture to make use of the new asm-generic/io.h to
provide address mapping functions. As nios2 actually performs
non-identity mapping between physical & virtual addresses we can't
simply make use of the generic functions, with the exception of being
able to drop our no-op unmap_physmem() and definitions of unused map
flags.
Feedback from architecture maintainers is welcome.

Zap ioremap(), as it is replaced by map_physmem(,,MAP_NOCACHE).

As virt_to_phys() is used a lot in DMA transfer, change it
to use physaddr_mask in global data. This will save an "if"
statement and get a little faster.

As the virtual address and physical address mapping of nios2 with
MMU are different. Add a check of MMU, and fix the mapping.

Convert ioremap() to use io_region_base in dm cpu global data.
Also remove three unused io functions, which have style issue
and are replaced by macros already.

These macros can be used to clear and set multiple bits
in a register using a single call.

Add ioremap() to map physical address to uncached virtual
address. We need this to convert the reg address from the
device tree.
The order of headers inclusion in interrupts.c is changed
because common.h will include board header that contains
IO_REGION_BASE.
In the future, the IO_REGION_BASE should be decided from
the device tree.

This helps to clean up the include/ directory so that it only contains
non-architecture-specific headers and also matches Linux's directory
layout which many U-Boot developers are already familiar with.
