[U-Boot] [RFC][PATCH v2 14/19] nand_fsl_nfc: get rid of local var

[Heiko Schocher]

If we have -fPIC enabled, this var leads in one entry in the
GOT. The result of this is that the image size is > 0x800.
So make it a "static const" and this brings the size again < 0x800

- changes since v1
  add comment from Scott Wood:
  - make the var nfc static const
