ci_nxp_build_failure: SDHC disk performance and FATFS fail on frdm_imx91

## Describe the bug NXP upstream CI reports build failures for the SDHC disk-performance tests and FATFS sample on `frdm_imx91/mimx9131` at the Zephyr main commit below. Affected test cases: - `drivers.disk.disk_performance.sdhc.disk_performance.random_read` - `drivers.disk.disk_performance.sdhc.disk_performance.random_write` - `drivers.disk.disk_performance.sdhc.disk_performance.sequential_read` - `drivers.disk.disk_performance.sdhc.disk_performance.sequential_write` - `sample.filesystem.fat_fs` ## Regression No regression range or bisect result is available. ## Steps to reproduce 1. Check out `c5dffcb7c9da611b40a828f79fc6a8405416c1ed` from Zephyr `main`. 2. Run the affected test suites for `frdm_imx91/mimx9131` with Twister. 3. Observe the build failures. For example: ```sh scripts/twister -p frdm_imx91/mimx9131 --build-only --inline-logs \ -s drivers.disk.disk_performance.sdhc.disk_performance.random_read scripts/twister -p frdm_imx91/mimx9131 --build-only --inline-logs \ -s sample.filesystem.fat_fs ``` ## Relevant log output The retained CI failure summary records `Build failure` for each affected case, but does not retain the compiler or linker diagnostic.
