Dan Carpenter 3ae39e99e5 i3c: Fix a shift wrap bug in i3c_bus_set_addr_slot_status() ...

commit 476c7e1d34 upstream.

The problem here is that addr can be I3C_BROADCAST_ADDR (126).  That
means we're shifting by (126 * 2) % 64 which is 60.  The
I3C_ADDR_SLOT_STATUS_MASK is an enum which is an unsigned int in GCC
so shifts greater than 31 are undefined.
