There was a previous attempt to implement this "iproc NAND"
(see: http://patchwork.ozlabs.org/patch/505399), however, due to the
amount of changes required, it seemed better to implement the code
in a series of steps. This is the first step, where the "iproc_nand.c"
is essentially an empty file (with one function required to allow this
commit to build successfully).
RFC only - more changes are coming for "drivers/mtd/nand/iproc_nand.c"
Changes in v2:
- convert some CONFIG_* to Kconfig
