[ Upstream commit 16aed0a6520ba01b7d22c32e193fc1ec674f92d4 ]
Replace the hardcoded value 2, which indicates 2 bits for I3C address
status, with the predefined macro I3C_ADDR_SLOT_STATUS_BITS.
Improve maintainability and extensibility of the code.

[ Upstream commit f18f98110f2b179792cb70d85cba697320a3790f ]
The address slot bitmap is an array of unsigned long's which are the
same size as an int on 32-bit platforms but not 64-bit. Loading the
bitmap into an int could result in the incorrect status being returned
for a slot and slots being reported as the wrong status.

put_device() needs to be called on failure of device_register()
to give up the reference initialized in it to avoid refcount leak.
