DESCRIPTION
Allocate and initialize basic ATA host resources. LLD calls this
function to allocate a host, initializes it fully and attaches it using
ata_host_register.
max_ports ports are allocated and host->n_ports is initialized to
max_ports. The caller is allowed to decrease host->n_ports before
calling ata_host_register. The unused ports will be automatically freed
on registration.
RETURNS
