Patch for sys/arch/powerpc/oea/ofwoea_machdep.c

[Wojciech Galazka <wgalazka.dev%gmail.com@localhost>]

Hi,
Please consider this patch.
Without this patch kernel panics on a PowerMac machine with PPC_601
cpu. installed. This is because real time clock is handled using
different opcodes on PPC_601 than on other 32 bit PPC_60x processors.
