    ahci: fix PORTS_IMPL override
    If PORTS_IMPL register is zero, ahci initialize it to full mask
    corresponding to nr_ports in the CAP register.  hpriv->cap, which is
    initialized at the end of the function, is incorrectly used as value
    of CAP causing ahci to always override PORTS_IMPL to 0x1 if it's zero.
    Fix it.
    This fixes a bug where early ich6 ahci can only access the first port.
