mtd: rawnand: ndfc: add CONFIG_OF dependency

When compile-testing on x86 without CONFIG_OF, the ndfc driver produces
a harmless warning:

drivers/mtd/nand/raw/ndfc.c: In function 'ndfc_probe':
include/linux/dev_printk.h:154:31: error: 'len' is used uninitialized [-Werror=uninitialized]
  154 |         dev_printk_index_wrap(_dev_err, KERN_ERR, dev, dev_fmt(fmt), ##__VA_ARGS__)
      |                               ^
drivers/mtd/nand/raw/ndfc.c:196:17: note: in expansion of macro 'dev_err'
  196 |                 dev_err(&ofdev->dev, "unable read reg property (%d)\n", len);

Limit compile-testing to configurations with CONFIG_OF to trivially
avoid this. The driver will still be built in allmodconfig and many
randconfig builds.
