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.
