* Make readv/writev implementations update struct uio
This can simplify partial result handling.
* change the error number on the overflow from EOVERFLOW to EINVAL
to match NetBSD
* add a commented out uio_offset field. I used "#if 0" here as
C comments can't nest.
* add a few helper functions
Note on uio_copyfrom/uio_copyto:
although i'm not quite happy with the "offset" functionality,
it's necessary to simplify the adaptation of some drivers like
drivers/serial/serial.c, which (ab)uses the user-supplied buffer
as a line-buffer.

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

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.)
newsize = newsize + CONFIG_FS_TMPFS_FILE_ALLOCGUARD;
When newsize is a large value,
adding a relatively small value can cause the result to become very small,
resulting in program logic errors.
For example:
0xffffffff + 0x2 = 1

This reverts commit 37104bf185dbf1665fc57f4ad039672e5c97c1dd.
Reason for revert: <This patch will cause specific product's a7 to fail to execute up_clean_dcache_all()>
When executing up_fbinitialize, the driver may turn on the vsync interrupt. If the vsync interrupt calls fb_pollnotify before executing fb->vtable->priv = fb it will cause null pointer access and crash.

- Fix DMA addressing issues within litex_sendsetup/litex_recvsetup
- Extend with handling specific to eMMC commands during init & use.
- Cleanup of 4-bit BUS handling for SD and eMMC
- For eMMC, Send CMD0 during init as per JEDEC v4.41 for pre-idle
The current implementation requires the use of enter_critical_section, so the source code needs to be moved to kernel space

The current implementation of PIO Interrupt for Allwinner A64 is incomplete. This PR fixes the implementation of PIO Interrupt for all supported PIO Ports (PB, PG and PH).
### Modified Files
`arch/arm64/src/a64/a64_pio.c`, `a64_pio.h`: Add implementation of PIO Interrupt
`arch/arm64/include/a64/irq.h`: Add IRQ for PIO Port PH
`arch/arm64/src/a64/hardware/a64_pio.h`: Fix addresses of PIO Interrupt Registers
When trying to use iperf2, we found it comsumes all the IOB when sending UDP packets, then devif_poll has no IOB to send the packet out, so speed drops to 0 and never recovers.

ECG sensors usually output some status info besides ECG data, such as lead and fast-recovery status. Thus a new member "status" is added into sensor_ecg struct.
