Originally, commit d7157ff49a5b ("mtd: rawnand: Use the ECC framework
user input parsing bits") kind of broke the logic around the
initialization of several ECC engines.
Unfortunately, the fix (which indeed moved the ECC initialization to
the right place) did not take into account the fact that a different
ECC algorithm could have been used thanks to a DT property,
considering the "Hamming" algorithm entry a configuration while it was
only a default.
Add the necessary logic to be sure Hamming keeps being only a default.

- Support HW ECC(one step is 1KB).
- Support 2 - 32K page size.
- Support 8 CS(depend on SoCs)
Limitations:
- No support for the ecc step size is 512.
- Untested on some SoCs.
- No support for subpages.

SDX55 uses QPIC version 2.0.0 IP for the NAND controller support.
In this version, DEV_CMD_* registers are moved to operational state,
hence CPU access in BAM mode is restricted. So, skip accessing these
registers and also use a different config for reading ONFI parameters.

pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. If runtime of the device has
error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, it will result in reference leak in
the two functions(gpmi_init and gpmi_nfc_exec_op). Moreover,
this device cannot enter the idle state and always stay busy or
other non-idle state later. So we fixed it through adding
pm_runtime_put_noidle.

struct mtd_info has a flag oops_panic_write which is set when the write
operation is issued via the panic_write() callback. That allows controller
drivers to distinguish the panic write from a regular write.
Replace the open coded 'in_interrupt() | oops_in_progress' checks with a
check for that flag. in_interrupt() is an unrealiable indicator anyway as
it covers all sorts of atomic contexts not only hard and soft interrupt
service routines.

This patch enables NAND MDMA (MBUS DMA) mode for
the Allwinner SoCs A23/A33/H3.
The DMA transfer method gets sets now to MBUS DMA as default for
the sun8i-a23-nand-controller (till now DMA transfer was executed
via the shared DMA engine).
The main advantage is more bandwidth for the users of the shared DMA
engine and also that the MBUS DMA setup requires less configuration
effort. For example you don't need to define a dedicated DMA channel
in the device-tree any more.

These functions must be usable by the main NAND core, so their names
must be technology-agnostic as well as the parameters. Hence, we pass
a generic nand_device instead of a raw nand_chip structure.
As it seems that changing the raw NAND functions to always pass a
generic NAND device is a lost of time, we prefer to create dedicated
raw NAND wrappers that will be useful in the near future to do the
translation.
