drivers/ide/pci/generic: fix build for CONFIG_HOTPLUG=n

It turns out that const and __{dev}initdata cannot be mixed currently
and that generic IDE PCI host driver is also affected by the same issue:

This patch workarounds the problem in a bit hackish way but without
removing const from generic_chipsets[] (it adds const to __setup() so
__setup_str_ide_generic_all becomes const).

Now all __{dev}initdata data in generic IDE PCI host driver are read-only
so it builds again (driver's .init.data section gets marked as READONLY).
