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 new mlxfw code fails to build without the xz library:
drivers/net/ethernet/mellanox/mlxfw/mlxfw_mfa2.o: In function `mlxfw_mfa2_xz_dec_run':
:(.text.mlxfw_mfa2_xz_dec_run+0x8): undefined reference to `xz_dec_run'
drivers/net/ethernet/mellanox/mlxfw/mlxfw_mfa2.o: In function `mlxfw_mfa2_file_component_get':
:(.text.mlxfw_mfa2_file_component_get+0x218): undefined reference to `xz_dec_init'
:(.text.mlxfw_mfa2_file_component_get+0x2c0): undefined reference to `xz_dec_end'
This adds a Kconfig 'select' statement for it, which is also what
the other user of that library has.

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.
