[PATCH] habanalabs: Elide a warning on 32-bit targets

[Palmer Dabbelt]

From: Palmer Dabbelt <palmer at rivosinc.com>

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.
