ARM: 8593/1: cache-l2x0.c: Do not clear bit 23 in prefetch control register
As per L2C-310 TRM[1]: "... You can control this feature using bits 30,27 and 23 of the Prefetch Control Register. Bit 23 and 27 are only used if you set bit 30 HIGH..." which means there is no need to clear bit 23 if bit 30 is being cleared.
