When a controller is running at full SDR speed at 12.5MHz, there needs
to be enough time for the processor get around to writing more data in
the fifo. Previously at -1 the size, this was enough for 1MHz with a
decent processor, but not enough at a 12.5MHz SCL.

The cadence i3c ip requires it's retaining registers to be updated
when a device is detached or attached.

There are some needs to attach and reattach i3c/i2c devices at runtime
Some I2C devices can have special registers where the address can be
changed at runtime. Also some I3C devices can be powered off at runtime
freeing up the address space they take up. These new APIs allow for these
to be changed at runtime. This also moves some config/data in to a common
i3c config/data structure which would allow the api to operate on to be
common for all I3C drivers.

This adds the reattach api necessary for writing the i3c retaining
registers within the cdns i3c when the dynamic address changes.

Some I3C controllers have retaining registers which are used to contain
the DA of the i3c device. This needs to be updated every time the DA is
updated with SETNEWDA or SETDASA

Unify the drivers/*/Kconfig menuconfig title strings to the format
"<class> [(acronym)] [bus] drivers".
Including both the full name of the driver class and an acronym makes
menuconfig more user friendly as some of the acronyms are less well-known
than others. It also improves Kconfig search, both via menuconfig and via
the generated Kconfig documentation.

According to section 5.1.9.3.5 and 5.1.9.3.6 of the I3C Specification
v1.1.1. This CCC is may be optionally supported if the target device
has no settable limit.

Rename is_primary to is_secondary. The justification for this is
because it is less likely to have something configured to be
secondary, and the 0 value would be if it is primary.

This adds a very basic driver to utilize the I3C IP block
on MCUX (e.g. RT685). Note that, for now, this only supports
being the active controller on the bus.

Adds support for a global workqueue so drivers can defer
IBI callbacks instead of doing it in interrupt context.

This introduces the I3C API for I3C controllers. Currently,
this supports one controller per bus under Zephyr.
