[MTD] [NAND] tmio_nand: fix base address programming
Fix offset of second word used for programming base address of memory window. Also program tmio with offset of the FCR, not with physical memory location. Signed-off-by: Dmitry Baryshkov <dbaryshkov@gmail.com> Cc: Ian Molton <spyro@f2s.com> Signed-off-by: David Woodhouse <David.Woodhouse@intel.com>
