spi: Fix tegra20 build with CONFIG_PM=n once again
Commit efafec27c565 ("spi: Fix tegra20 build with CONFIG_PM=n") already fixed the build without PM support once. There was an alternative fix by Guenter in commit 2bab94090b01 ("spi: tegra20-slink: Declare runtime suspend and resume functions conditionally"), and Mark then merged the two correctly in ffb1e76f4f32 ("Merge tag 'v5.15-rc2' into spi-5.15"). But for some inexplicable reason, Mark then merged things _again_ in commit 59c4e190b10c ("Merge tag 'v5.15-rc3' into spi-5.15"), and screwed things up at that point, and the __maybe_unused attribute on tegra_slink_runtime_resume() went missing. Reinstate it, so that alpha (and other architectures without PM support) builds cleanly again. Btw, this is another prime example of how random back-merges are not good. Just don't do them. Subsystem developers should not merge my tree in any normal circumstances. Both of those merge commits pointed to above are bad: even the one that got the merge result right doesn't even mention _why_ it was done, and the one that got it wrong is obviously broken.
