The previous 1ms sleep introduced unnecessary latency
while waiting for the SUSPF flag.
Switching to a 750µs busy-wait provides a more responsive
and precise delay,improving performance in time-sensitive contexts.

Enable optional storage of sensor attribute values in EEPROM. On reset, the
device goes through a POR sequence that loads the values programmed in the
EEPROM into the respective register map locations.
The driver stores sample frequency, offset, oversampling, lower threshold,
upper threshold, alert pin polarity, alert mode and conversion mode if the
value is continuous or shutdown.
The functionality has been tested with sensor shell and power cycling
sensor:
Test (undocumented) temperature offset is stored:
```shell
uart:~$ sensor attr_set ti_tmp11x@48 ambient_temp offset 0
ti_tmp11x@48 channel=ambient_temp, attr=offset set to value=0
uart:~$ sensor get ti_tmp11x@48 ambient_temp
[...] (25.523436)
uart:~$ sensor attr_set ti_tmp11x@48 ambient_temp offset 50
ti_tmp11x@48 channel=ambient_temp, attr=offset set to value=50
uart:~$ sensor get ti_tmp11x@48 ambient_temp

uart:~$ sensor attr_get ti_tmp11x@48 ambient_temp offset
ti_tmp11x@48(channel=ambient_temp, attr=offset) value=50.000000
```
Test one-shot mode is not stored:

This Kconfig does not belong in the ADC folder, because there is not
actually a zephyr ADC driver for this. Also, remove HAS_MCUX_ADC_ETC as
well because it is a useless config.
The cmake line to pull in this driver from the SDK in the zephyr repo is
totally unnecessary. If a user wants to use this SDK driver they can add
it to their build like any other SDK driver or any other
external code module. Zephyr should not be a cesspool of random build
glue for random pieces of code.

There was actually three different types of configuration modes
happening here, and this function was getting extremely bulky and hard
to read due to the amount of nesting of conditionals. Split these into
separate functions and call them appropriately depending on the type of
transfer.

The dependency on the chosen node for dtcm can be expressed in Kconfig
language.
Cache we care about is CPU DCACHE, not the meaningless "MCUX Cache"
The macros can be reordered to be simpler by having only one level of
conditional (no nesting) instead of three levels.
Move this code closer in the file to where this cache attribute macro is
actually going to be used (the init macro) instead of randomly splitting
up the struct definitions at the top.

Use a mutex to protect the I2C bus from concurrent access. Replace busy
waiting with a binary semaphore. Process the messages in the interrupt
handler state machine to generate a single transaction. In the
interrupt handler, process the states until nothing more is to do. This
prevents superfluous interrupt entry/exit pairs. Return error
conditions to the caller. Check the messages for consistency and return
an error for unsupported message lists.

This commit introduces a new devicetree property, bits-per-symbol, to
allow the symbol width to be configured from 3 to 8 bits. This change
is particularly beneficial for MCUs that lack DMA for their SPI
peripheral and have a limited hardware FIFO.
This property provides flexibility by allowing developers to select a
slower SPI clock frequency and use the symbol width to scale the
timings to meet strict LED strip requirements, minimizing the risk of
FIFO underruns.
Additionally, using higher-density patterns (e.g., 3-bit or 4-bit
symbols) makes more efficient use of the pixel buffer, which reduces
the RAM footprint required for the LED strip data.
The implementation is optimized with a fast path for the common 8-bit
symbol case, while a generic bit-packing loop handles all other
widths.
