Two helpers have been added to the core to do all kind of controller
side configuration/initialization between the detection phase and the
final NAND scan. Implement these hooks so that we can convert the driver
to just use nand_scan() instead of the nand_scan_ident() +
nand_scan_tail() pair.

Miquel Raynal 7da45139d2 mtd: rawnand: better name for the controller structure
In the raw NAND core, a NAND chip is described by a nand_chip structure,
while a NAND controller is described with a nand_hw_control structure
which is not very meaningful.

Rename this structure nand_controller.

As the structure gets renamed, it is logical to also rename the core
function initializing it from nand_hw_control_init() to
nand_controller_init().

Lastly, the 'hwcontrol' entry of the nand_chip structure is not
meaningful neither while it has the role of fallback when no controller
structure is provided by the driver (the controller driver is dumb and
can only control a single chip). Thus, it is renamed dummy_controller.

Miquel Raynal acfc33091f mtd: rawnand: fsl_ifc: fix probe function error path
An error after nand_scan_tail() should trigger a nand_cleanup().
The helper mtd_device_parse_register() returns an error code that should
be checked and nand_cleanup() called accordingly.

However, in this driver, fsl_ifc_chip_remove() which is called upon
error already triggers a nand_release() which is wrong, because a
nand_release() should be triggered only if an mtd_register() succeeded.

Move the nand_release() call out of the fsl_ifc_chip_remove() and put it
back in the *_remove() hook.
