[-mm patch] more UID16 fixes

[-mm patch] more UID16 fixes

[Adrian Bunk]

It seems the "make UID16 support optional" patch was checked when it 
edited the -tiny tree some time ago, but it wasn't checked whether it
still matches the current situation when it was submitted for inclusion 
in -mm. This patch fixes the following bugs:
- ARCH_S390X does no longer exist, nowadays this has to be expressed
  through (S390 && 64BIT)
- in five architecture specific Kconfig files the UID16 options
  weren't removed

Additionally, it changes the fragile negative dependencies of UID16 to 
positive dependencies (new architectures are more likely to not 
require UID16 support).

Yeah, that's a better approach. Thanks.
