Workaround to avoid getting the -EFAULT (14) error when running
the test_spi_word_size_x (x = 7, 9, 24) test cases:
Since these testcase configurations aren't supported, update
the error type to ENOTSUP to allow skipping the test cases using ztest.

Place transfer buffers in non-cacheable memory when
CONFIG_NOCACHE_MEMORY=y. This change ensures that DMA transfer
buffers are allocated in non-cacheable memory on platforms where
CONFIG_NOCACHE_MEMORY is enabled. This avoids potential cache
coherence issues that are not handled by the SPI driver.

Set a convenient latency for each platform, since each platform
reacts differently to the driver.

The driver treats the `source_data_size` and `dest_data_size` as a
width in bits and converts 8 bits to 1, 16 bits to 2, and 32 bits to 3.
This should be a width in bytes with 1 byte mapping to 0, 2 bytes to
1, and 4 bytes to 3.
Note that this preserves the current behaviour of silently accepting
invalid transfer bit widths.

Some devices have multiple pinctrl regions; for instance, main pinctrl and
mcu pinctrl. Currently there can only be a single pinctrl instance picked
form a DT label. This patch makes the pinctrl driver initialise one
instance for each node with correct compatible string.

When uart_ns16550_irq_tx_enable() is called and the TX FIFO is already
empty, no new interrupt is generated, causing data transmission to stall
in some cases. This patch introduces a workaround to simulate an ISR
callback if the FIFO is empty when enabling the TX IRQ.

Clarify linking issues in PRs and Commit messages and address the issue
of ambiguity across multiple github repos.
Not allowing links in commit messages so that forks can be happy is not
great.
Forks on Github have no problem with linking, however,
disconnected forks seem to not link correctly, but then why does this
matter?
If someone is taking Zephyr and developing it as their own, they
can for sure do that, but why this should force the Zephyr project to
manage traceability differently and make it more difficult for
developers to add such information in the git metadata directly and not
relying on pull requests.
Most developers use git directly and rely less on pull request and
github UI when browsing changes in the code base.. We need to be able to
see by looking at git commits and git
history if a commit is associated with a bug, some PRs might fix
multiple issues, so the context is important and by looking at each
commit the trace can be established immesiately without going back to
github pull requests.
