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.
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.

Now that we have time conversion defines from in time.h there is no need
for each driver to define their own version.

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.

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
