The DAI interface is not used from user-space in all configurations
where Zephyr user-space is enabled, so it is beneficial to have
a build option to contorl whether the DAI syscalls are included or
not.

During reboot operations, interrupts are disabled but k_is_pre_kernel()
returns false, causing SCMI communication to fail when using interrupt
mode. Force polling mode to ensure reliable operation in all contexts.

Implement sys_arch_reboot() using SCMI system power protocol
for warm and cold reset operations on SCMI-enabled platforms.
Signed-off-by: Yongxu Wang <yongxu.wang@nxp.com>
Add SCMI System Power Domain Protocol support with:
- System power state set operations
- Standard SCMI power states (shutdown, cold/warm reset, suspend)
- Graceful and forceful power transitions
- Optional NXP vendor-specific power states
- Device tree binding for "arm,scmi-system"
This enables system-wide power management through standardized
SCMI interfaces for reboot and power control operations.

Add SCMI protocol version negotiation to handle compatibility between
different agent and platform versions. The negotiation automatically
downgrades to supported version when needed and maintains backward
compatibility with legacy systems.

Add standardized SCMI protocol common interface functions that can be
reused across different SCMI protocol implementations:
- scmi_protocol_get_version(): Query protocol version
- scmi_protocol_attributes_get(): Get protocol-specific attributes
- scmi_protocol_message_attributes_get(): Query message capabilities
- scmi_protocol_version_negotiate(): Negotiate protocol version support

Instead of having one "make_thread" function per instance, called through
a function pointer in the instance configuration, save the thread stack
information instead and consume it from shared code in the driver pre-init
function. This makes the driver more readable (less code in the instance
creation macro) and should reduce its footprint impact (since the thread
creation code is no longer duplicated).

Add support for the Zephyr device power management framework to
enable runtime power control of the ADXL345 accelerometer.
This implementation adds a pm_device_action callback that handles
SUSPEND and RESUME actions. When suspended, the sensor enters
standby mode for low power operation. On resume, it returns to
measurement mode.
The implementation follows the standard pattern used by other
sensor drivers (lis2dh, bme280, vcnl4040) and integrates with
the PM_DEVICE_DT_INST_DEFINE macro for automatic PM setup.
Tested on nRF52832 with CONFIG_PM_DEVICE enabled.

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.

This patch achieves that by:
- Waiting one second between each message sent by the host, so people
can actually follow what's going on;
- Wraping the content of the messages (strings "hello" and "world") in
quotes, so it's clear what they are;
- Toning down the logging to INF - no need for DBG;
- Removing astray `\n` - LOG_XXX already takes care of that.
