[PATCH] mtd: rawnand: brcmnand: Fix sparse warning in has_flash_dma()

[Florian Fainelli]

Sparse rightfully complained about has_flash_dma():
+drivers/mtd/nand/brcmnand/brcmnand.c:951:40: warning: Using plain integer as NULL pointer [sparse]

Fixes: 27c5b17cd1b1 ("mtd: nand: add NAND driver "library" for Broadcom STB NAND controller")
