5b15f8650b mtd: rawnand: Annotate implicit fall through in nand_command/nand_command_lp
There is a plan to build the kernel with -Wimplicit-fallthrough and
these places in the code produced warnings (W=1).

This commit removes the following warnings:

  drivers/mtd/nand/raw/nand_legacy.c:332:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
  drivers/mtd/nand/raw/nand_legacy.c:483:3: warning: this statement may fall through [-Wimplicit-fallthrough=]

7a08dbaedd mtd: rawnand: Move ->setup_data_interface() to nand_controller_ops
->setup_data_interface() is a controller specific method and should
thus be placed in nand_controller_ops.

In order to make that work with controllers that support keeping
pre-configured timings we need to add a new NAND_KEEP_TIMINGS flag to
inform the core it should skip the timings selection step.

f2abfeb207 mtd: rawnand: Move the ->exec_op() method to nand_controller_ops
->exec_op() is a controller method and has nothing to do in the
nand_chip struct. Let's move it to the nand_controller_ops struct and
adjust the core and drivers accordingly.

7d6c37e90c mtd: rawnand: Deprecate the ->select_chip() hook
Now that the CS line to be selected is passed to ->exec_op() and
stored in chip->cur_cs and after patching all drivers implementing
->exec_op() to stop implementing this method, we can deprecate it by
moving it to the nand_legacy structure.

996852a97b mtd: rawnand: legacy: Drop useless test in nand_legacy_set_defaults()
nand_legacy_set_defaults() returns directly if chip->exec_op != NULL,
no need to test !chip->exec_op after that.

0813621ba8 mtd: rawnand: Stop passing mtd_info objects to internal functions
After having reworked the rawnand API to avoid passing mtd_info
objects around, let's do the same for internal functions.

3d4af7c195 mtd: rawnand: Move legacy code to nand_legacy.c
Allows us to move a few hundred lines of deprecated code out of the
core file which is quite big.
