[William Zhang]

Fix the following sparse warnings:
sparse warnings: (new ones prefixed by >>)
>> drivers/mtd/nand/raw/brcmnand/bcmbca_nand.c:79:41: sparse: sparse:
cast removes address space '__iomem' of expression
   drivers/mtd/nand/raw/brcmnand/bcmbca_nand.c:80:17: sparse: sparse:
cast removes address space '__iomem' of expression
   drivers/mtd/nand/raw/brcmnand/bcmbca_nand.c:80:17: sparse: sparse:
cast removes address space '__iomem' of expression
   drivers/mtd/nand/raw/brcmnand/bcmbca_nand.c:80:17: sparse: sparse:
cast removes address space '__iomem' of expression

Fixes: c52c16d1bee5 ("mtd: rawnand: brcmnand: Add BCMBCA read data bus interface")
