This reverts commit 89172666228de1cefcacf5bc6f61c6281751d2ed which is upstream commit be4ae8c19492cd6d5de61ccb34ffb3f5ede5eec8.
This commit is causing a suspend regression on Tegra186 Jetson TX2 with Linux v6.12.y kernels. This is not seen with Linux v6.15 that includes this change but indicates that there are there changes missing. Therefore, revert this change.
