ahci: DMA addressing fixes
Ensure that we are using correct physical/virtual address for
DMA buffer write and hardware register settings.
The convention is: in ahci_ioports all pointers are virtual,
that will be converted to physical address when writing to
hardware registers or into sg/cmd_tbl.
Also fixed 64bit physical address support for dwc_ahsata, ensure
higher bits are written into registers/sg properly.
Use memalign for allocating aligned buffer in dwc_ahsata so we
don't have to do our own alignment in driver.
