First set of u-boot-at91 features for the 2023.04 cycle:
This feature set includes the new DM-based NAND flash driver (old non-DM
driver is still kept for backwards compatibility), and the move to DM
NAND flash driver for sam9x60ek board. Feature set also includes
devicetree alignment for sama7g5 with Linux, devicetree alignment on USB
with Linux for all boards (sama5, sam9x60), chip id for sama7g5, minor
configs and tweaks.
Add the CONFIG_SYS_NAND_SELF_INIT to the Kconfig to follow the changes from
mainline.

This is always defined to 16K, so we move this over to
include/fsl_validate.h to start with. Next, we rename this from CONFIG_
to FSL_. Coalesce the various comments around this definition to be in
fsl_validate.h as well to explain the usage.

Upstream linux commit 69fc01296c9281
commit a1286a1fc4 ("mtd: nand: Move Samsung specific init/detection
logic in nand_samsung.c") introduced a regression for Samsung SLC NAND
chips. Prior to this commit chip->bits_per_cell was initialized by calling
nand_get_bits_per_cell() before using nand_is_slc().
With the offending commit this call is skipped, leaving
chip->bits_per_cell cleared to zero when the manufacturer specific
'.detect' function calls nand_is_slc() which in turn interprets
bits_per_cell != 1 as indication for an MLC chip.
The effect is that e.g. a K9F1G08U0F NAND chip is falsely detected as
MLC NAND with 4KiB page size rather than SLC with 2KiB page size.
Add a call to nand_get_bits_per_cell() before calling the .detect hook
function in nand_manufacturer_detect(), so that the nand_is_slc()
calls in the manufacturer specific code will return correct results.

Add driver for atmel pmecc. This implementation is ported from
Linux. The reference taken is linux-5.4-at91.

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

The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do
not easily transition to Kconfig. In many cases they likely should come
from the device tree instead. Move these out of CONFIG namespace and in
to CFG namespace.

This converts the following to Kconfig:
CONFIG_SYS_NAND_DBW_8
CONFIG_SYS_NAND_DBW_16
Note that all instances of the code check for CONFIG_SYS_NAND_DBW_16
being defined, and then "else" to CONFIG_SYS_NAND_DBW_8 whereas all of
the configs set CONFIG_SYS_NAND_DBW_8. So we introduce
CONFIG_SYS_NAND_DBW_16 as an option.
