* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert
host drivers + drivers/ide/setup-pci.c to use it instead of calling
ide_init_port_hw() directly (however if host has more than 1 port we
must still set hwif->chipset to hint consecutive ide_find_port() call
that the ide_hwifs[] slot is occupied).
* Unexport ide_init_port_hw().
There should be no functional changes caused by this patch.
