Regressions on the arm64, builds failed with gcc-8 on Linux stable-rc
6.12.13-rc1. But the gcc-13 and clang builds pass.

This was also reported on Linus tree a few weeks back [1] and also seen on
the stable-rc 6.13.2-rc1

Build regression: arm64, gcc-8 phy-fsl-samsung-hdmi.c __compiletime_assert_537

Good: v6.12.11
Bad: 6.12.13-rc1 (v6.12.11-634-g9ca4cdc5e984)
