While vfio-platform itself is on a reprieve from being removed[1],
these reset drivers don't support any current hardware, are not being
tested, and suggest a level of support that doesn't really exist.
Mark them for removal to surface any remaining user such that we can
potentially drop them and simplify the code if none appear.

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.

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.

This patch adds Broadcom FlexRM low-level reset for
VFIO platform.
It will do the following:
1. Disable/Deactivate each FlexRM ring
2. Flush each FlexRM ring
The cleanup sequence for FlexRM rings is adapted from
Broadcom FlexRM mailbox driver.

This patch introduces a module that registers and implements a low-level
reset function for the AMD XGBE device.
it performs the following actions:
- reset the PHY
- disable auto-negotiation
- disable & clear auto-negotiation IRQ
- soft-reset the MAC
Those tiny pieces of code are inherited from the native xgbe driver.

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.
