Re-enable various config options disabled by name changes:
- SUNRPC_XPRT_RDMA replaced SUNRPC_XPRT_RDMA_{CLIENT,SERVER}
- [mips*el/loongson*] LOONGSON64 replaced LOONGSON
- [x86] COMEDI_8255_SA replaced COMEDI_8255
Drop explicit settings for symbols that are now automatic.
Use kconfigeditor2/process.py to put all definitions in Kconfig order
with proper headings.
Delete all definitions of unknown config symbols, which I verified
have been removed (or made automatic) upstream and not renamed.
