i2c: mlxbf: remove device tree support
BlueField customers have to use the BlueField firmware with UEFI ACPI tables so there is no need to have device tree support in the i2c-mlxbf.c driver. Remove the device tree binding documentation as well. Signed-off-by: Asmaa Mnebhi <asmaa@nvidia.com> Reviewed-by: Khalil Blaiech <kblaiech@nvidia.com> Signed-off-by: Wolfram Sang <wsa@kernel.org>
