The DT bindings for the Renesas FLCTL NAND controller document only support a
single SoC, namely the Renesas R-Mobile AP4 (SH7372).
Linux dropped support for this SoC in commit 59b89af1d5551c12 ("ARM:
shmobile: sh7372: Remove Legacy C SoC code") in v4.1.

The FLCTL NAND controller (or an enhanced version) is also present on
SH-Mobile AG5 (sh73a0) and R-Mobile A1 (r8a7740), but the sole boards
supported upstream (KMC KZM-A9-GT resp. Atmark Techno Armadillo-800-EVA)
use eMMC NAND instead of raw NAND FLASH.
What's the policy w.r.t. stale DT bindings?
Should it be converted to json-schema instead?
drivers/mtd/nand/raw/sh_flctl.c still implements these bindings.
The driver cannot be removed, as it is also used on the non-DT
SH7723-based AP-325RXA platform.

-FLCTL NAND controller
-
-Required properties:
-- compatible : "renesas,shmobile-flctl-sh7372"
-- reg : Address range of the FLCTL
-- interrupts : flste IRQ number
-- nand-bus-width : bus width to NAND chip
-
-Optional properties:
-- dmas: DMA specifier(s)
-- dma-names: name for each DMA specifier. Valid names are
- "data_tx", "data_rx", "ecc_tx", "ecc_rx"
-
-The DMA fields are not used yet in the driver but are listed here for
-completing the bindings.
-
-The device tree may optionally contain sub-nodes describing partitions of the
-address space. See partition.txt for more detail.
-
-Example:
-
- flctl@e6a30000 {
- #address-cells = <1>;
- #size-cells = <1>;
- compatible = "renesas,shmobile-flctl-sh7372";
- reg = <0xe6a30000 0x100>;
- interrupts = <0x0d80>;
-
- nand-bus-width = <16>;
-
- dmas = <&dmac 1 /* data_tx */
- &dmac 2;> /* data_rx */
- dma-names = "data_tx", "data_rx";
-
- system@0 {
- label = "system";
- reg = <0x0 0x8000000>;
- };
-
- userdata@8000000 {
- label = "userdata";
- reg = <0x8000000 0x10000000>;
