The default MCUX_OS_TIMER_MIN_DELAY of 1000 cycles is too large
relative to CYC_PER_TICK (100) on platforms clocked at 1 MHz with
SYS_CLOCK_TICKS_PER_SEC=10000. Because MIN_DELAY exceeds CYC_PER_TICK
by 10x, nearly every sys_clock_set_timeout() call adds an extra tick,
inflating short delays and causing the kernel timer_behavior test
(timer_ramp) to fail for low delay values.
Reduce the default to 50 cycles (50 us at 1 MHz), which provides
sufficient hardware setup margin for the match register without
interfering with normal tick scheduling.
Verified on frdm_mcxa344 and frdm_mcxa156 hardware:

The init sequence never put the coprocessor into station mode, so on a
freshly flashed module the first AT+CWJAP is rejected with ERROR and
wifi connect always fails.
Issue AT+CWMODE=1,1 during initialization. This matches ST's ST67W6X
SDK, which sets station mode in W61_WiFi_Station_Start(), called early in
W6X_WiFi_Init() (before auto-connect, country code and DTIM setup). The
auto-connect field is left at the firmware default (1) so mode changes
rely on the saved flash configuration.

The I2C master transfer waited on the transfer semaphore with K_FOREVER,
so a target that never completed a transfer would block the calling
thread indefinitely with no recovery mechanism.
Wait on the transfer semaphore using I2C_TRANSFER_TIMEOUT. On a timeout,
abort the asynchronous operation and reset the shared state with the SCB
interrupt masked so a late completion cannot corrupt the teardown, then
return -ETIMEDOUT.

A write-read transfer to a target that NACKs its address sometimes
returns stale data on alternating attempts. This is caused by the read
phase being chained from the interrupt handler whenever the master goes
idle. After a write is aborted by an address NACK, the read is still
being issued, which causes an extra completion to be signalled. The
following transfer then erroneously acts on this, causing the driver to
report a successful transfer erroneously.
Chain the read phase from the event handler on write completion so it is
only issued after the write phase is successful. Clear the async
transfer state on the error path so the interrupt handler doesn't start
a spurious read after a failed write.

Deconfigure: i2s_configure() with frame_clk_freq == 0 is defined by the
API as a request to deconfigure the stream, but the driver rejected it
with -EINVAL. Release the queued buffers and move the stream to
NOT_READY. The state check is now made on the stream being configured
instead of on both directions at once, so one direction can be
configured while the other one is running, and config_get() returns
NULL for an unconfigured stream as the API requires.
Restart: reset the FIFO pointers via the FR bit before enabling DMA
requests, so words left over from a previous run are not replayed.

This base commit provides the core acquisition-path driver:
- Full BioZ acquisition-path configuration from devicetree (clock/PLL,
drive, receive channel, digital filters, thresholds, mux, DC leads and
lead bias), with a dt-bindings header of MAX30009_DT_* constants for
the enumerated properties.
- Runtime attribute access (attr_set / attr_get) for the meaningful BioZ
parameters via a descriptor table, cycling the PLL where the datasheet
requires the acquisition path to be quiesced.
- Power management (suspend / resume) following the datasheet's
bandgap / PLL / channel enable sequence.
Trigger and RTIO streaming support are added in follow-up commits; the
full Kconfig describing those options is included here so the driver's

The val_out snapshot exported by elapsed() was written after the
wrap-realignment step, so callers received last_load instead of 0
whenever sample C happened to read VAL == 0.
sys_clock_set_timeout() feeds that snapshot into the drift
compensation as val1 and compares it against a later raw read of
SysTick->VAL as val2. Mixing a realigned operand with a raw one makes
val1 - val2 evaluate to a whole counter period that never elapsed, so
cycle_count jumps forward by up to one full timer period on every
reprogram that lands on a zero VAL sample.
The realignment of 0 to last_load is an internal convention of
elapsed(): it exists only so the wrap-detection below can assume
COUNTFLAG and wrapping occur on the same cycle. It has no meaning for
a caller that measures a window against its own raw register read.
Move the export to immediately after the three register reads so
val_out carries the raw sample, which is what the code did before
elapsed() grew the out-parameter. The out-parameter still removes the
gap between the window elapsed() accounts for and the window the
drift compensation measures.
