ARM: remove w90x900 platform
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.
