* Add 'hw_regs_t **hws' argument to ide_device_add[_all]() and convert
host drivers + ide_legacy_init_one() + ide_setup_pci_device[s]() to use
it instead of calling ide_init_port_hw() directly.
[ However if host has > 1 port we must still set hwif->chipset to hint
consecutive ide_find_port() call that the previous slot is occupied. ]
* Unexport ide_init_port_hw().
v2:
* Use defines instead of hard-coded values in buddha.c, gayle.c and q40ide.c.
(Suggested by Geert Uytterhoeven)
* Better patch description.
v3:
* Fix build problem in ide-cs.c. (Noticed by Stephen Rothwell)
There should be no functional changes caused by this patch.
