Merge patch series "fs: Remove old mount API helpers"

Pedro Falcato <pfalcato@suse.de> says:

This patchset contains a very small cleanup, where we remove mount_nodev
(unused since 6.15) and mount_bdev (unused since f2fs converted their
mount API usage, still in -next). While we're at it, we also get to
removing some stale mount API docs.
