net: ax25: remove plumbing for never-implemented DAMA Master support
The AX25_DAMA_MASTER option has been unimplemented and marked broken
ever since it was introduced in 2007 in commit 954b2e7f4c37 ("[NET]
AX.25 Kconfig and docs updates and fixes"). At this point, it is very
unlikely it will be implemented. Remove it.
