vfio/platform: Cleanup Kconfig Like vfio-pci, there's also a base module here where vfio-amba depends on vfio-platform, when really it only needs vfio-platform-base. Create a sub-menu for platform drivers and a nested menu for reset drivers. Cleanup Makefile to make use of new CONFIG_VFIO_PLATFORM_BASE for building the shared modules and traversing reset modules.

vfio: Use kconfig if XX/endif blocks instead of repeating 'depends on' This results in less kconfig wordage and a simpler understanding of the required "depends on" to create the menu structure. The next patch increases the nesting level a lot so this is a nice preparatory simplification.

vfio: Split virqfd into a separate module for vfio bus drivers An unintended consequence of commit 42ac9bd18d4f ("vfio: initialize the virqfd workqueue in VFIO generic code") is that the vfio module is renamed to vfio_core so that it can include both vfio and virqfd. That's a user visible change that may break module loading scritps and it imposes eventfd support as a dependency on the core vfio code, which it's really not. virqfd is intended to be provided as a service to vfio bus drivers, so instead of wrapping it into vfio.ko, we can make it a stand-alone module toggled by vfio bus drivers. This has the additional benefit of removing initialization and exit from the core vfio code. Signed-off-by: Alex Williamson <alex.williamson@redhat.com>

VFIO: platform: Calxeda xgmac reset module This patch introduces a module that registers and implements a basic reset function for the Calxeda xgmac device. This latter basically disables interrupts and stops DMA transfers. The reset function code is inherited from the native calxeda xgmac driver.
