Merge tag 'u-boot-at91-2024.04-a' of https://source.denx.de/u-boot/custodians/u-boot-at91

First set of u-boot-at91 features for the 2024.04 cycle:

This set includes some DT alignments and solves a compile issue for
custom nand defconfigs.

a1c6b08274 mtd: nand: raw: atmel: Remove duplicate definitions
These removed definitions were specific to some sam9 SoCs, but not
generic over all at91 SoCs.  The correct SoC specific definitions for
ATMEL_BASE_PMECC are spread over different header files in
arch/arm/mach-at91/include/mach directory.

Fixes a build error on a custon board based on SAMA5D2:

38cc6cdeb1 Merge patch series "Import "string" I/O functions from Linux"
To quote the author:

This series imports generic versions of ioread_rep/iowrite_rep and
reads/writes from Linux. Some cleanup is done to make sure that all
platforms have proper defines for implemented functions and there are no
redefinitions.

fa34fbf9a1 asm-generic: Import functions from Linux
Currently {read,write}s{b,w,lq}() functions are available only on some
architectures, and there are no io{read,write}{8,16,32,64}_rep()
functions in u-boot. This patch adds generic versions that may be used
without arch-specific implementation.

Since some of added functions were already added locally in some files,
remove them to avoid redeclaration errors.

13248d66ae treewide: use linux/time.h for time conversion defines
Now that we have time conversion defines from in time.h there is no need
for each driver to define their own version.

d6b4359e50 mtd: nand: raw: atmel: Add error handling when rb-gpios missing
Adapt behaviour to Linux kernel driver.

The return value of gpio_request_by_name_nodev() was not checked before,
and thus in case 'rb-gpios' was missing in DT, rb.type was set to
ATMEL_NAND_GPIO_RB nevertheless, leading to output like this for
example (on sam9x60-curiosity with the line removed from dts):

    NAND:  Could not find valid ONFI parameter page; aborting
    device found, Manufacturer ID: 0xc2, Chip ID: 0xdc
    Macronix NAND 512MiB 3,3V 8-bit
    512 MiB, SLC, erase size: 256 KiB, page size: 4096, OOB size: 64
    atmel-nand-controller nand-controller: NAND scan failed: -22
    Failed to probe nand driver (err = -22)
    Failed to initialize NAND controller. (error -22)
    0 MiB

Note: not having that gpio assigned in dts is possible, the driver does
not override nand_chip->dev_ready() then and a generic solution is used.

6a8dfd5722 nand: atmel: Add DM based NAND driver
This implementation is ported from the rework done by Boris Brezillon
in Linux. This porting is done based on linux-5.4-at91. The driver is
tested in sam9x60ek, sama5d3_xplained, sam9x75eb and sama7g54-ddr3-eb.

Changes done includes

- Adapt GPIO descriptor apis for U-Boot. Use gpio_request_by_name_nodev,
  dm_gpio_get_value etc.
- Use U_BOOT_DRIVER instead of platform_driver.
- Replace struct platform_device with struct udevice
- Check the status of nfc exec operation by polling the status
  register instead of interrupt based handling
- DMA operations not supported. Remove it
- Adapt DT parsing to U-Boot APIs
