[PATCH] mtd: pxa3xx_nand: fix compilation error

[Linus Walleij]

When building the pxa3xx defconfig without device tree support
(i.e. the pxa3xx_defconfig) the build fails like this:

drivers/mtd/nand/pxa3xx_nand.c: In function ‘pxa3xx_nand_probe’:
drivers/mtd/nand/pxa3xx_nand.c:1325:2: error: implicit declaration of function ‘pxa3xx_nand_get_variant’ [-Werror=implicit-function-declaration]
  info->variant = pxa3xx_nand_get_variant(pdev);
  ^
cc1: some warnings being treated as errors
make[5]: *** [drivers/mtd/nand/pxa3xx_nand.o] Error 1
make[4]: *** [drivers/mtd/nand] Error 2
make[4]: *** Waiting for unfinished jobs....

Fix it up by returning the PXA variant on non-DT boots.

This appears to have been broken since
commit c0f3b8643a6fa2461d70760ec49d21d2b031d611
"mtd: nand: pxa3xx: Introduce 'marvell,armada370-nand' compatible string"
