Fix UV call into kgdb to depend only on whether KGDB is defined and not
both KGDB and KDB. This allows the power nmi command to use the gdb
remote connection if enabled. Note new action of 'kgdb' needs to be set
as well to indicate user wants to wait for gdb to be connected. If it's
set to 'kdb' then an error message is displayed if KDB is not configured.

Note that if both KGDB and KDB are enabled, then the action of 'kgdb' or
'kdb' has no affect on which is used. See the KGDB documention for further
information.
