Subject: [PATCH] accel/habanalabs: add more debugfs stub helpers

From: Arnd Bergmann <arnd@...db.de>

Two functions got added with normal prototypes for debugfs, but not
alternative when building without it:

drivers/accel/habanalabs/common/device.c: In function 'hl_device_init':
drivers/accel/habanalabs/common/device.c:2177:14: error: implicit declaration of function 'hl_debugfs_device_init'; did you mean 'hl_debugfs_init'? [-Werror=implicit-function-declaration]
drivers/accel/habanalabs/common/device.c:2305:9: error: implicit declaration of function 'hl_debugfs_device_fini'; did you mean 'hl_debugfs_remove_file'? [-Werror=implicit-function-declaration]

Add stubs for these as well.

Fixes: 553311fc7b76e ("accel/habanalabs: expose debugfs files later")
