First, I implemented this driver as per-bank model, but it was
a design mistake.
- There are 31 banks in the maximum case. It is painful to add
so many nodes to DT.
- The IRQ control registers are shared between banks. Per-bank
design is a problem for Linux. The counterpart for Linux turned
around to the single node model.
Rework based on the driver for Linux.

Set Features (0xEF) command toggles the R/B# pin after 4 sub feature
parameters are written.
Currently, nand_command(_lp) calls chip->dev_ready immediately after
the address cycle because NAND_CMD_SET_FEATURES falls into default:
label. No wait is needed at this point.
If you see nand_onfi_set_features(), R/B# is already cared by the
chip->waitfunc call.

We have at least a minor count of boards, that failed to re-initialize
PCI express in the Linux kernel. Typical failure rate is 20% on affected
boards. This is mitigated by commit 6ecbe1375671 ("drivers: pci: imx:
add imx_pcie_remove function").
However, at least on some i.MX6 custom boards, when calling
assert_core_reset() as part of the first-time PCIe init, read access
to PCIE_PL_PFLR simply hangs. Surround this readl() with
imx_pcie_fix_dabt_handler() does not help. For this reason, the forced
LTSSM detection is only used on the second assert_core_reset() that is
called shorly before starting the Linux kernel.

The livetree codepath of ofnode_get_addr_size always used the "reg"
property for of_get_property. Use the property parameter of the function
call instead and check the return value if the property exists.
Otherwise return FDT_ADDR_T_NONE.
This was discoverd while using SPI NOR with livetree.
spi_flash_decode_fdt checks for memory-map and will not fail with
livetree even if the property does not exist.

In U-Boot -ENODEV means that there is no device. When there is a problem
with the device, drivers should return an error like -ENXIO or -EREMOTEIO.
When the device tree properties cannot be read correct , they should
return -EINVAL.

for future driver writers.

These three drivers all use U_BOOT_DEVICE rather than device tree to
create devices, so have to do manual allocation of platform data. This is
not true for new platforms.

It does not look like this driver needs to use a bind() method. It does
not manually create devices with device_bind() nor does it create devices
using U_BOOT_DEVICE(). It seems to only use device tree.
Therefore the manual allocation of platform data is not needed and is
confusing. Also platform data should be set up by the ofdata_to_platdata()
method, not bind().
Update the driver in case others use it as a model in future.

Use the new helper function to avoid boilerplate in the driver.
Note that this changes __raw_writel et al. to writel. AFAICT this is
no problem because:
- The Linux driver for the same hardware uses the non-__raw variants as
well (via pci_generic_config_write()).
- This driver seems to be used only on MIPS so far, where the __raw and
non-__raw accessors are the same.
