soc/intel/baytrail/sata.c: Fix SATA init sequence
SeaBIOS on Bay Trail would time out when trying to access a SATA drive. Turns out that there's two mistakes in the SATA initialization sequence: - PCI register 0x94 is wrongly cleared with a bitwise-and operation. - PCI register 0x9c is instead written to 0x98, clobbering the latter. After correcting them, SeaBIOS can boot from SATA on Asrock Q1900M.
