Thomas Petazzoni 01becc082d arch/Config.in.x86: drop knightslanding and knightsmill archs
According to the GCC 14.x release notes at
https://gcc.gnu.org/gcc-14/changes.html:

  Xeon Phi CPUs support (a.k.a. Knight Landing and Knight Mill) are
  marked as deprecated. GCC will emit a warning when using the
  -mavx5124fmaps, -mavx5124vnniw, -mavx512er, -mavx512pf,
  -mprefetchwt1, -march=knl, -march=knm, -mtune=knl or -mtune=knm
  compiler switches. Support will be removed in GCC 15.

Using those architectures already emits warnings, which when treated
as errors cause build failures, such as:

  cc1: error: '-march=knm' support will be removed in GCC 15 [-Werror=deprecated]
  cc1: all warnings being treated as errors

Therefore, let's drop support for those two architectures, which are
anyway not common at all, especially in the embedded space.

Fixes:
