Fix for bug:
https://github.com/zephyrproject-rtos/zephyr/issues/59575
The dma version of the version of the driver can
invoke multiple intermediate dma transfers, like
when the spi_buf_set count is greater than one.
However, there is a bug where chip select is not kept
asserted for all intermediate dma transfers required
to process the entire spi_buf_set.

Avoid integer overflow in temp_sq calculation.
For an analysis of the value ranges for the temp_sq calculation
of mx5837-02 see below:
calculation:
dT = adc_temperature - ((int32_t)(data->t_ref) << 8);
data->temperature = 2000 + (dT * data->tempsens) / (1ll << 23);
temp_sq = (data->temperature - 2000) * (data->temperature - 2000);
given needed storage sizes:
t_ref is uint16_t,
adc_temperature is uint24_t,
data->tempsens is uint16_t,
ranges
=> dT: -16776960 <= dT <= 16777215 (25 bit)
=> data->temperature (TEMP):
intermed.(mult): -1099478073600 <= x <= 1099494785025 (41 bit)
TEMP: 2.000 - 131068 <= TEMP <= 2.000 + 131.069
TEMP: -129068 <= TEMP <= 133069 (17 bit)
So worst case we need 17 bit for TEMP, so the square of it would
overflow an int32_t. The nominal measurement range is
only -40 to 85°C, meaning a range of -4000 to 8500.
So normally the result for temp_seq would fit into a int32_t,
but we cast to be better safe than sorry. Also the 64-bit
multiplication won't be the dominating operation of the
whole calculation.

This change introduces the "_rtc_timer" suffix for the system tick timer
driver "compatible" property and aligns naming conventions with the
actual CC13/26xx SoC series product policy.
This frees up the "_rtc" namespace to introduce additional APIs based on
the same peripheral in the future (not part of this PR):
rtc: rtc@... {
compatible = "ti,cc13xx-cc26xx-rtc";
...
timer {
compatible = "ti,cc13xx-cc26xx-rtc-timer";
...
};
counter {
compatible = "ti,cc13xx-cc26xx-rtc-counter";
...
};
pps {
compatible = "ti,cc13xx-cc26xx-rtc-pps";
...
};
};
Or alternatively an MFD pattern with similar requirements.
Fixing the namespacing now makes sense standalone as it reduces the
chance of custom drivers being broken in the future.
Redundant extension of the mandatory system clock devicetree node is
replaced with a single `status = "okay"` which seems to be the more
sensible default to avoid user error when defining custom boards.
Knowledgeable users can still override this if really needed.

The ISM330DHCX driver immediately segfaults when run in SPI mode. A bad
pointer is being passed into the `dev` param of `ism330dhcx_spi_read`.
Tracing this back, it appears that the handle field of the ctx struct
is being set to the device's data struct while `ism330dhcx_spi_read`
expects `ctx->handle` to be a pointer to a device struct.
Modify `ism330dhcx_spi_init()` to insert the correct pointer into the
context struct. Unfortunately this requires a cast to discard the
`const` qualifier, but this is how it is done in I2C mode (see
`ism330dhcx_i2c_init()`). The only other way would be to change the
declaration of `stmdev_ctx_t`, which is owned by the HAL module.

gpio_nrfx_port_get_direction() is meant to check which inputs
are enabled, and does so by checking one bit at a time
and setting that bit into the "input" parameter.
But "input" was never zeroed, so any garbage ones it
may have remains.
Zero it.
This fixes a problem where if the "input" parameter was not
zeroed by the caller, the result of the funcion call
is undefined.
