i3c: master: Replace hard code 2 with macro I3C_ADDR_SLOT_STATUS_BITS
[ 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.
