Subject: [PATCH] habanalabs: fix build warning

allmodconfig build fails on ARCH=xtensa with the following message:

  drivers/misc/habanalabs/common/memory.c:153:49: error: cast from pointer
	to integer of different size [-Werror=pointer-to-int-cast]
	(u64) gen_pool_dma_alloc_align(vm->dram_pg_pool,

Fix it by adding intermediate conversion to uintptr_t as in other places
in that driver.

Fixes: e8458e20e0a3 ("habanalabs: make sure device mem alloc is page aligned")
