Regressions on mips defconfig tinyconfig and allnoconfig builds failed with
clang-20 toolchain on stable-rc  6.14.7-rc1, 6.12.29-rc1 and 6.6.91-rc1.
But, builds pass with gcc-13.

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

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