instead of kconfig macros, making it more flexible for different
spi/i2c instances.

1. rework IOM cmdq buffer instantiation
2. rework spi and i2c cache handling as it is incorrect.
3. buffers need to be aligned with DCACHE on

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.

During init i2c_ambiq device, the bitrate calculation is not correct,
results in incorrect device speed, or failed to configure i2c device
if clock-frequency is set to higher than I2C_BITRATE_STANDARD
