[PATCH] mtd: nand/raw: MTD_NAND_BCM47XXNFLASH needs CONFIG_BCMA

[Arnd Bergmann]

We already have a dependency on BCMA_NFLASH, which in turn depends on
BCMA, but since BCMA is a tristate option and BCMA_NFLASH is bool,
we can run into an invalid configuration with MTD_NAND_BCM47XXNFLASH=y
and BCMA=m:

drivers/mtd/nand/raw/bcm47xxnflash/ops_bcm4706.o: In function `bcm47xxnflash_ops_bcm4706_init':
ops_bcm4706.c:(.text+0x790): undefined reference to `bcma_chipco_pll_read'

Adding the dependency here forces MTD_NAND_BCM47XXNFLASH to only be
configured =m here so it can link against the BCMA driver.
