ide: fix host drivers missing hwif->chipset initialization
ide_find_port() now depends on ->chipset being set for occupied ide_hwifs[]
slots so all host drivers have to initialize hwif->chipset properly.
This patch fixes a regression on hosts with > 1 port or with a single port
but no devices attached to it for an affected host drivers.
