Regressions on mips defconfig tinyconfig and allnoconfig builds failed with
clang-20 toolchain on stable-rc 6.6.91-rc1, 6.14.7-rc1 and 6.12.29-rc1.
But, builds pass with gcc-12.

* mips, build
  - clang-20-allnoconfig
  - clang-20-defconfig
  - clang-20-tinyconfig

Regression Analysis:
 - New regression? Yes
 - Reproducibility? Yes

Build regression: mips defconfig clang-20 instantiation error expected
an immediate
