ata_host_alloc9
Allocate and init basic ata host resources
Usage

Arguments
dev
generic device this host is associated with
max_ports
maximum number of ATA ports associated with this host
Overview
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.
Return
Allocate ATA host on success, NULL on failure.
LOCKING: Inherited from calling layer (may sleep).
