firewire: core: clean up config ROM related defined constants
Clemens Ladisch pointed out that
- BIB_IMC is not named like the field is called in the standard,
- readers of the code may get worried about the magic 0x0c0083c0,
- a CSR_NODE_CAPABILITIES key is there in the header but not put to
good use.
So let's rename BIB_IMC, add a defined constant for Node_Capabilities
and a comment which reassures people that somebody thought about it and
they don't have to (or if they still do, tell them where they have to
look for confirmation), and prune our incomplete and arbitrary set of
defined constants of CSR key IDs. And there is a nother magic number,
that of Bus_Information_Block.Bus_Name, to be defined and commented.
