AHCI - Chip reset, Inquiry alignment, ATAPI adjustments, Intel attach
* When resetting the chip set AE before issuing HR and leave AE set
when issuing HR. After reset is complete, set AE again.
* Do Intel hocus pocus at config register 0x92 for Intel chipsets.
* The only PIO request is basically the initial INQUIRY during probe.
Make sure the structure does not cross a page boundary so only one
DRQ buffer is needed. Very old AHCI chipsets may need this.
* Make minor flags adjustments for PIO setup commands during the
initial probe.
* Reduce verbosity slightly.
