As discussed previously, these two ARM platforms have no
known remaining users, let's remove them completely.

Subsystem maintainers: feel free to take the driver removals
through your respective trees, they are all independent of
one another. We can merge any remaining patches through the
soc tree.

ks8695 is an older SoC originally made by Kendin, which was later acquired
by Micrel, and subsequently by Microchip.

The platform port was originally contributed by Andrew Victor and Ben
Dooks, and later maintained by Greg Ungerer.

When I recently submitted cleanups, but Greg noted that the platform no
longer boots and nobody is using it any more, we decided to remove it.

	Arnd Bergmann, Russell King

This removes the old Winbond w90x900 platform, also known
as Nuvoton NUC900. Wan Zongshun originally contributed
the port and maintained it since then.

From all I can tell, this platform is no longer being used
with modern kernels, based on various indications:

- The supported chips (nuc910/950/960) are no longer marketed
  by the manufacturer

- Newer chips from the same family (nuc97x, nuc980, n329x)
  that are still marketed have Linux BSPs but those were never
  submitted for upstream inclusion.

- The last patch from the platform maintainer was in 2011.

- All patches to w90x900 platform specific files afterwards
  are cleanups that were apparently done without access to
  test hardware.

- Both the website and the email address listed in the
  MAINTAINERS have become unreachable.
