[PATCH v2 0/2] Convert FSMC NAND controller driver to ->exec_op()

Now that the ->exec_op() interface has been merged in the NAND core,
convert the FSMC NAND controller driver to it.

A previous step involves getting rid of ->IO_ADDR_[R|W] across the
driver, which is almost entirely done in the first patch. Because the
driver still uses at that point the default implementations of
->read/write_byte/word(), some references are still present but are
removed as soon as the driver is moved to ->exec_op(), when this
dependency disappears.

Best regards,

Changes since v1:

- Forgot about the NAND unique ID for now, this will need a deeper
  rework of the MTD stack and is very (ONFI-)NAND-specific.
- Split the migration of FSMC driver to ->exec_op() into two patches,
  one to get rid of ->IO_ADDR_[R|W], the other to implement ->exec_op()
  and ->select_chip() which is also needed.
- Got rid of the additional ->regs entry in the FSMC structure, using
  the existing entry ->regs_va instead.

  mtd: nand: fsmc: get rid of IO_ADDR_[R|W]
  mtd: nand: fsmc: use ->exec_op()
