Log Message:
ahcisata_pci: Add sanity check for BAR5 to prevent panic

 Inte volume management can't be attach to ahcisata_pci.
It doesn't conform the AHCI specification. The AHCI specification says it's
32bit BAR. According to the PCI specification, if a BAR is the lower 32-bit
register of a 64-bit register, the next register represents the upper 32
bits. However, BARs only go up to 5, and there is no BAR 6.
