openfirmware: remove real_time_clock.

Browse Source 
It is used only in the TCP loader to initialize a random TCP source port.
Since the RTC device does not exist on sparc, this is not portable. A
simple solution is to use a non-random source port, maybe based on the
powercycle count or something like that. For now, I don't need the TCP
loader, so I'll just disable this.
