If CONFIG_I2C_STATS is enabled, the device state for all I2C controller
drivers must contain the I2C stats. This space is allocated by calling
Z_I2C_INIT_FN as part of the device definition; this is done automatically
when using I2C_DEVICE_DT_DEFINE instead of DEVICE_DT_DEFINE. If space
for statistics is not properly allocated but CONFIG_I2C_STATS is enabled,
an unexpected write to memory outside of the stats region may occur on
an I2C transfer. This commit uses I2C_DEVICE_DT_DEFINE or
I2C_DEVICE_DT_INST_DEFINE for all in-tree SPI controller drivers that do
not already.

Use the RTIO work queue to fake the i2c submit calls for drivers which
haven't yet implemented the API. Applications can change the size of
the work queue pool depending on how much traffic they have on the buses.

This change marks each instance of the 'i2c_driver_api' as 'static const'.
The rationale is that 'i2c_driver_api' is used for declaring internal
module interfaces and is not intended to be modified at runtime.
By using 'static const', we ensure immutability, leading to usage of only
.rodata and a reduction in the .data area.

Use GPIO_OUTPUT_INACTIVE to initialize the pin so that the ACTIVE_LOW DT
flag is honored and use the gpio_pin_set_dt functions to set the
(logical) value of the pin instead of gpio_pin_configure_dt, that
tries to reconfigure the pin each time.
