sata_highbank: clear whole array in highbank_initialize_phys()
The original code used the wrong parameter to clear tx_atten[]. It passed the number of elements instead of sizeof() the array to memset. The other potential issue was that cphy_base[] wasn't cleared. I'm not sure if that was a real problem or not, but I have cleared it in my patch. Instead of using memset(), this patch uses empty initializers as a cleanup.
