This double-cast pattern looks a bit awkward, but it already exists
elsewhere in the driver. Without this patch I get
drivers/misc/habanalabs/common/memory.c: In function ‘alloc_device_memory’:
drivers/misc/habanalabs/common/memory.c:153:49: warning: cast from pointer to integer of different size [-Wpointer-to-int-cast]
153 | (u64) gen_pool_dma_alloc_align(vm->dram_pg_pool,
| ^
which ends up promoted to a build error in my test setup.

I don't know anything about this driver, I'm just pattern-matching the
warning away.
