i3c: dw: use FIELD_PREP for device address table macros
Add DEV_ADDR_TABLE_DYNAMIC_MASK / DEV_ADDR_TABLE_DYNAMIC_ADDR(x) for
dynamic device addresses and DEV_ADDR_TABLE_STATIC_MASK /
DEV_ADDR_TABLE_STATIC_ADDR(x) for static device addresses in the I3C
address table. Replace manual shift-and-mask with FIELD_PREP() for both
dynamic and static addresses for clarity and maintainability.
