ahci: alloc structs in high memory

With ahci running in 32bit mode we can also allocate the
(ahci private) data structures in high memory.  This
reduces the real mode memory footprint as we only need
to move struct ahci_port_s (which contains struct drive_s)
to fseg in case the port probe was successful.
