gpu: host1x-fence: Fix build for Linux v6.2

Upstream Linux kernel commit ff62b8e6588f ("driver core: make struct
class.devnode() take a const *") updated the 'devnode' function pointer
under the class structure to take a const device struct. This breaks
building the Tegra host1x-fence driver with Linux v6.2. Make the
necessary changes to the host1x-fence driver to fix the build breakage.
