Initialize the i2c config of the emulator based on the clock_frequency
property.
The emulator can be used without calling the i2c_configure function, but
the i2c_get_config would return an error. With this change, it is
possible to get the config prior to the i2c_configure call.

This register is a pre-define hardware slave A and can be accessed
through I2C0. It is not currently used, so it can be disabled to
avoid illegal access.

Helpers like dev_cfg have been removed from all in-tree drivers, this
one was missed.

Use the IF_ENABLED macro helper to conditionally initialize the int_gpio
field. This avoids duplication of initialization code.

The device instance can be obtained at compile time. Here
DEVICE_DT_GET_OR_NULL is used as the following code seems to accept a
NULL condition, meaning instance is optional.

Simplify driver implementation by using spi_dt_spec. Most internal
functions now take a device reference to simplify the operation, since
config did not exist before.

The device already has a DT compatible (and uses DT properties).
Instantiate the device using the DT-based macros and remove hardcoded
name.

Simplify driver implementation by using spi_dt_spec. Note that driver
has 2 SPI configurations, identical except the speed. For this reason,
the slow config is still kept in RAM and copied from the one obtained
via the SPI dt_spec macros. A better solution would be to have macros
that allow to override the SPI frequency, but this can be improved
later. Most internal helpers have been adjusted to accept a device
reference to make SPI (and future GPIO) transition easier.

Simplify driver implementation by using gpio_dt_spec. To simplify
migration, all internal functions now take a device reference instead of
device data. As a result, the redundant config pointer in data has been
removed.

Simplify the driver implementation by using gpio_dt_spec. Note that most
internal functions have been changed to accept a device instance instead
of data/config references to make transition easier and to align with
