fix: Allow BuffaloZclDataType for AttributeDefinition.type

[Koenkk]

Already allow for parameter and now also for the AttributeDefinition. Required for Koenkk/zigbee-herdsman-converters#9711

[Nerivec]

Need to change Attribute too.
It opens up the code paths a little, though I suppose it all ends up in BuffaloZcl read/write. Might want to add a test or two just in case though, make sure calls with both types are covered.

Closing this PR as this won't work for reading (only writing), when reading the type is included in the ZCL payload.
