[PATCH 07/13] hw/ide: Extract pci_ide_{cmd, data}_le_ops initialization into base class constructor

[Bernhard Beschow <shentey@gmail.com>]

There is redundant code in cmd646 and via which can be extracted into the base
class. In case of piix and sii3112 this is currently unneccessary but shouldn't
interfere since the memory regions aren't mapped by those devices. In few
commits later this will be changed, i.e. those device models will also make use
of these memory regions.
