Masahiro Yamada 2127982895 mtd: rawnand: vf610_nfc: add initializer to avoid -Wmaybe-uninitialized
This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place.  We need to eliminate potential issues beforehand.

Kbuild test robot has never reported -Wmaybe-uninitialized warning for
this probably because vf610_nfc_run() is inlined by the x86 compiler's
inlining heuristic.

If CONFIG_OPTIMIZE_INLINING is enabled for a different architecture and
vf610_nfc_run() is not inlined, the following warning is reported:

  drivers/mtd/nand/raw/vf610_nfc.c: In function `vf610_nfc_cmd':
  drivers/mtd/nand/raw/vf610_nfc.c:455:3: warning: `offset' may be used uninitialized in this function [-Wmaybe-uninitialized]
     vf610_nfc_rd_from_sram(instr->ctx.data.buf.in + offset,
     ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
              nfc->regs + NFC_MAIN_AREA(0) + offset,
              ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
              trfr_sz, !nfc->data_access);
              ~~~~~~~~~~~~~~~~~~~~~~~~~~~
