Update kernel to 5.5.2
Between 5.4 and 5.5, apparently in commit 0e4a459f56c32d3e ("tracing:
Remove unnecessary DEBUG_FS dependency"), CONFIG_DEBUG_FS is no longer
auto-enabled. We're using that interface for obtaining an old-school
GPIO number because, well, that's what the LED GPIO trigger expects.
It would be nice to fix this upstream so that the LED GPIO trigger
accepts, say, a (chipname, gpio number) pair, but ENOTIME.
