[PATCH] gpu: host1x: Remove unused functions

[Mikko Perttunen <mperttunen@nvidia.com>]

Remove the host1x_fence_create_fd and host1x_fence_extract
functions that are not used anywhere. host1x_fence_create_fd
is additionally using sync_file_create without there being
a Kconfig dependency to SYNC_FILE, causing builds to fail.
