Add support for attributes composed from few registers. Such attributes could occupy from 2 to 4 sequential registers. For word size register space complex attributes can occupy up to two registers, for byte size - up to four. These attributes can carry, for example, CPLD or FPGA versioning, power consuming info, etcetera. Such registers contain read-only data.
