dt-bindings: i3c: Add mipi-i3c-static-method to support SETAASA

Add the 'mipi-i3c-static-method' property mentioned in the MIPI I3C
Discovery and Configuration Specification [1] to specify which discovery
method an I3C device supports during bus initialization. The property is
a bitmap, where a bit value of 1 indicates support for that method, and 0
indicates lack of support.

Bit 0: SETDASA CCC (Direct)
Bit 1: SETAASA CCC (Broadcast)
Bit 2: Other CCC (vendor / standards extension)
All other bits are reserved.

It is specifically needed when an I3C device requires SETAASA for the
address assignment. SETDASA will be supported by default if this property
is absent, which means for now the property just serves as a flag to
enable SETAASA, but keep the property as a bitmap to align with the
specifications.
