Subject: [PATCH 2/3] mtd: atmel nand: fix build warning on 64-bit

Build-testing this driver on a 64-bit architecture produces a
harmless warning:

drivers/mtd/nand/raw/atmel/nand-controller.c: In function 'atmel_smc_nand_controller_init':
drivers/mtd/nand/raw/atmel/nand-controller.c:2053:21: error: cast from pointer to integer of different size [-Werror=pointer-to-int-cast]

To cast the pointer correctly, the destination type should be
uintptr_t rather than a 32-bit int.

Fixes: c2f3d0b913a5 ("mtd: rawnand: atmel: Allow selection of this driver when COMPILE_TEST=y")
