Change type of address parameter from int* to volatile void* for
{read,write}s{b,w,l}() functions and add const qualifier for reads. This
is done to keep function signatures in sync with asm-generic/io.h and
other platforms.

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

This imports mmio functions from Linux's arch/riscv/include/asm/mmio.h
to use read/write[b|w|l|q]_relaxed functions.

Clean up asm/io.h by
- removing commented code
- removing outdated comments
- removing unused definitions (for mem_isa, mem_pci)
This massively improves the readability of the file.
Suggested by commits:
7ab2e47d27c9 ("arm: Clean up asm/io.h")
909d0399a519 ("ARM: asm/io.h: kill off confusing #ifdef __mem_pci block")

Commit ba1ed5b022c6 ("Convert CONFIG_ARCH_MAP_SYSMEM to Kconfig") clearly
defined that this option is available for SANDBOX (was also for already
removed NDS32). That's why there is no way how this code can be enabled
with current Kconfig layout for riscv.
Based on this removing this code.

This patch adds memcpy_fromio and memcpy_toio definitions for some device
drivers which have these definitions, like cadence_qspi_apb.c

io read/write may cause wrong result because they may read/write data
from/to register instead of memory. Add 'volatile' to avoid it.

RISC-V U-Boot reimplements the generic io functions from
asm-generic/io.h. Remove the redundant implementation and include the
generic io.h instead.

Replace the barrier functions in arch/riscv/include/asm/io.h with those
defined in barrier.h, which is imported from Linux. This version is
modified to remove the include statement of asm-generic/barrier.h, which
is not available in U-Boot or required.

The RISC-V arch incorrectly uses 32-bit instead of 64-bit variables in
several places. Fix this.
In addition, BITS_PER_LONG is set to 64 on RV64I systems.

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.
