Allow movement detection to be used on hardware
that only has one interrupt line connected.

Both DRDY and motion interrupts behaves like level signals since they
remain asserted until they're cleared. Configuring them as edge
interrupts is dangerous because if we ever miss an interrupt, it may
never get cleared and thus will never trigger again.
Treating them as edge signals seems to have no advantages, other than
being marginally simpler to implement.
The patch has gotten many hours of run-time on real hardware using a
nRF52-based board and a LIS3DH with both interrupts connected and
heavily utilized.

Use gpio_dt_spec structure and related macros for both drdy
and AnyMotion interrupts, to have a more compat, readable and
safe code. Moreover, skip setting DRDY or AnyMotion trigger
from application if the corresponding irq-gpios has not been set.

Currently there is no way to distinguish between a caller
explicitly asking for a semaphore with a limit that
happens to be `UINT_MAX` and a semaphore that just
has a limit "as large as possible".
Add `K_SEM_MAX_LIMIT`, currently defined to `UINT_MAX`, and akin
to `K_FOREVER` versus just passing some very large wait time.
In addition, the `k_sem_*` APIs were type-confused, where
the internal data structure was `uint32_t`, but the APIs took
and returned `unsigned int`. This changes the underlying data
structure to also use `unsigned int`, as changing the APIs
would be a (potentially) breaking change.
These changes are backwards-compatible, but it is strongly suggested
to take a quick scan for `k_sem_init` and `K_SEM_DEFINE` calls with
`UINT_MAX` (or `UINT32_MAX`) and replace them with `K_SEM_MAX_LIMIT`
where appropriate.

After switching to new SPI API there is no need to reserve first dummy
byte in buffer and ignore that in application later on. Instead two
buffers can be specified, which is how it is done already in lis2dh
driver. The problem is that dummy byte is still part of the buffer, but
it clearly should no longer be. As an example we write 0x7 (bits to
enable XYZ axes) into CTRL2 instead of CTRL1 register. When reading
measurements on the other hand we have filled buffer starting from 0,
instead of 1 as the driver code has expected.
Fix driver in all places that use burst transfers by removing first
dummy byte from input/output buffer.
