Improve the pci ivshmem device compatibility, do not return error when
irq mode init failed, fallback to the polling mode as mush as possible.

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

This patch fixed userspace headers conflict. Architecture-related definition and API should not be exposed to users.

currently, nuttx implements readv/writev on the top of read/write.
while it might work for the simplest cases, it's broken by design.
for example, it's impossible to make it work correctly for files
which need to preserve data boundaries without allocating a single
contiguous buffer. (udp socket, some character devices, etc)
this change is a start of the migration to a better design.
that is, implement read/write on the top of readv/writev.
to avoid a single huge change, following things will NOT be done in
this commit:
* fix actual bugs caused by the original readv-based-on-read design.
(cf. https://github.com/apache/nuttx/pull/12674)
* adapt filesystems/drivers to actually benefit from the new interface.
(except a few trivial examples)
* eventually retire the old interface.
* retire read/write syscalls. implement them in libc instead.
* pread/pwrite/preadv/pwritev (except the introduction of struct uio,
which is a preparation to back these variations with the new
interface.)
ivshmem based driver can use this api to judge weather current
ivshmem device support irq or not, and use polling mode or irq
mode to process the event.

1. add IS_ALIGNED() definitions for NuttX;
2. replace all the ALIGN_UP() and ALIGN_DOWN() to use common
align implementation;
