Removed last argument 'secondary' and restructured
i3c_master_register to move code that can be common
to i3c_secondary_master_register to separate function
i3c_master_init.

Main changes between v8 and v9 are:
- Fix NULL dereference issue in current_master_show when
cat'ing sysfs key current_master for secondary master
before primary master gets initialized.
Main changes between v7 and v8 are:
- Document format changed from table to DOT diagram
- Appropriate names for few functions
- Moved mastership request process entirely to the driver
- Reuse of i3c_master_add_i3c_dev_locked in core defslvs
processing
Main changes between v6 and v7 are:
- Added separate functions for main and secondary
master initialization
- Secondary master initialization don't wait for
DEFSLSVS.
- Change to use I2C device information from DTS,
and corresponding changes in controller driver
and I3C core DEFSLVS processing to ignore I2C
devices received in DEFSLVS
- Reverted bus_init split
- Fixed formatting issues in document
Main changes between v5 and v6 are:
- Moved populate_bus() hook to master subsystem code.
- For secondary master initialization i3c_master_register
spawan separate threads, as secondary master may have to
wait for DEFSLVS and bus mastership.
- Populate bus info is based on DEFSLVS data and take care
of hot plugged / unplugged I3C devices.
- Split bus_init into bus_init and master_set_info callbacks
- Moved mastership aquire and handover to separate state
machines.
- Added DEFSLVS processing code.
- Moved back all locks in side the subsystem code.
- Secondary mastership support to Cadence I3C master
controller driver
- Sysfs key 'i3c_acquire_bus' to acauire bus.
- NULL check for pool pointer in i3c_generic_ibi_free_pool.
Main changes between v4 and v5 are:
- Add populate_bus() hook
- Split i3c_master_register into init and register pair
- Split device information retrieval, let add partialy discovered devices
- Make i3c_master_set_info private
- Add separate function to register secondary master
- Reworked secondary master register in CDNS driver
- Export i3c_bus_set_mode
Main changes between v3 and v4 are:
- Reworked acquire bus ownership
- Refactored the code
Main changes between v2 and v3 are:
- Added DEFSLVS devices are registered from master driver
- Reworked I2C registering on secondary master side
- Reworked Mastership event is enabled/disabled globally (for all devices)
Main changes between initial version and v2 are:
- Reworked devices registration on secondary master side
- Reworked mastership event disabling/enabling
- Reworked bus locking during mastership takeover process
- Added DEFSLVS devices registration during initialization
- Fixed style issues

i3c: master: master initialization flow document
i3c: master: use i3c_master_register only for main master
i3c: master: add i3c_secondary_master_register
i3c: master: add mastership handover support
i3c: master: add defslvs processing
i3c: master: sysfs key for acquire bus
i3c: master: mastership handover, defslvs processing in cdns
