[PATCH 24/46] mtd: nandsim: Wire up NANDSIM_MODE_CACHEFILE ioctl mode

[Daniel Walter]

From: Richard Weinberger <richard@xxxxxx>

Allow the userspace control tool also to setup a cache file.
In contrast to the cache_file module parameter the ioctl() only
accepts a fd. So, userspace should hand in an fd pointing to
a temp file.
