The declaration of struct devlink in general header provokes the
situation where internal fields can be accidentally used by the driver
authors. In order to reduce such possible situations, let's reduce the
namespace exposure of struct devlink.

Expose fsm_reactivate callback to the mlxfw_dev_ops struct. FSM reactivate
is needed before flashing the new image in order to flush the old flashed
but not running firmware image.
In case mlxfw_dev do not support the reactivation, this step will be
skipped. But if later image flash will fail, a hint will be provided by
the extack to advise the user that the failure might be related to it.

Introduce mlxfw_{info, err, dbg} macros and make them call corresponding
dev_* macros, then convert all instances of pr_* to mlxfw_*.
This will allow printing the device name mlxfw is operating on.

FW flash status notify is currently implemented via a callback to the
caller mlx module, and all it is doing is to call
devlink_flash_update_status_notify with the specific module devlink
instance.
Instead of repeating the whole process for all mlx modules and
re-implement the status_notify callback again and again. Just provide the
devlink instance as part of mlxfw_dev when calling mlxfw_firmware_flash
and let mlxfw do the devlink status updates directly.
This will be very useful for adding status notify support to mlx5, as
already done in this patch, with a simple one line of just providing the
devlink instance to mlxfw_firmware_flash.
mlxfw now depends on NET_DEVLINK as all other mlx modules.

Add new op status_notify which is called to update the user about
flashing status.

Currently the error messages are printed to dmesg. Propagate them also
to directly to user doing the flashing through extack.

If mlx5 is set to be built-in and mlxfw as a module, we
get a link error:
drivers/built-in.o: In function `mlx5_firmware_flash':
(.text+0x5aed72): undefined reference to `mlxfw_firmware_flash'
Since we don't want to mandate selecting mlxfw for mlx5 users, we
use the IS_REACHABLE macro to make sure that a stub is exposed
to the caller.

There are upcoming NIC (mlx5) use-cases where people want to avoid
building the mlxfw module, allow for that. The mlxsw module is
untouched and keeps selecting mlxfw.

The mlxfw module is in charge of common logic needed to flash Mellanox
devices firmware, which consists of:
- Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is
the format used to store the Mellanox firmware. The MFA2 format file can
hold firmware for many different silicon variants, differentiated by a
unique ID called PSID. In addition, the MFA2 file data section is
compressed using xz compression to save both file-system space and
memory at extraction time.
- Implement the firmware flash state machine logic, which is a common
logic for Mellanox products needed to flash the firmware to the device.
As the module is shared between different Mellanox products, it defines a
set of callbacks to be implemented by the specific driver for hardware
interaction.
