> 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.
