Subject: [PATCH] spi: spi-qpic: fix common module build

From: Arnd Bergmann <arnd@...db.de>

When the NAND driver is a loadable module, and the SPI driver is
turned off, the common part is not built:

ERROR: modpost: "qcom_nandc_unalloc" [drivers/spi/spi-qpic-snand.ko] undefined!
ERROR: modpost: "qcom_write_reg_dma" [drivers/spi/spi-qpic-snand.ko] undefined!
ERROR: modpost: "qcom_read_reg_dma" [drivers/spi/spi-qpic-snand.ko] undefined!

ERROR: modpost: "qcom_write_data_dma" [drivers/spi/spi-qpic-snand.ko] undefined!

Simplify the Makefile to just build the common bits for either of the two,
so it will be built-in whenever one of them is, or otherwise a loadable
module if needed.
