misc/habanalabs: adjust Kconfig to fix build errors

Several places in the habanalabs driver use gen_alloc functions,
so select GENERIC_ALLOCATOR to make those functions available.

Fixes these build errors:

ERROR: "gen_pool_alloc" [drivers/misc/habanalabs/habanalabs.ko] undefined!
ERROR: "gen_pool_add_virt" [drivers/misc/habanalabs/habanalabs.ko] undefined!
ERROR: "gen_pool_destroy" [drivers/misc/habanalabs/habanalabs.ko] undefined!
ERROR: "gen_pool_create" [drivers/misc/habanalabs/habanalabs.ko] undefined!
ERROR: "gen_pool_free" [drivers/misc/habanalabs/habanalabs.ko] undefined!
