ide: dynamic allocation of device structures
Allocate device structures dynamically instead of having them embedded
in ide_hwif_t:
* Remove needless zeroing of port structure from ide_init_port_data().
* Add ide_hwif_t.devices[MAX_DRIVES] (table of pointers to the devices).
* Add ide_port_{alloc,free}_devices() helpers and use them respectively
in ide_{host,free}_alloc().
* Convert all users of ->drives[] to use ->devices[] instead.
While at it:
* Use drive->dn for the slave device check in scc_pata.c.
As a nice side-effect this patch cuts ~1kB (x86-32) from the resulting
code size:
