ide: fix PowerMac bootup oops
PowerMac bootup with CONFIG_IDE=y oopses in ide_pio_cycle_time():
because "ide: try to use PIO Mode 0 during probe if possible" causes
pmac_ide_set_pio_mode() to be called before drive->id has been set.
Bart points out other places which now need drive->id set earlier,
so follow his advice to allocate it in ide_port_alloc_devices()
(using kzalloc_node, without error message, as when allocating drive)
and memset it for reuse in ide_port_init_devices_data().
Fixed in passing: ide_host_alloc() was missing ide_port_free_devices()
from an error path.
