    i2c: mlxbf: support BlueField-3 SoC · 19e13e13

    BlueField-3 SoC has the same I2C IP logic as previous
    BlueField-1 and 2 SoCs but it has different registers' addresses.
    This is an effort to keep this driver generic across all
    BlueField generations.
    This patch breaks down the "smbus" resource into 3 separate
    resources to enable us to use common registers' offsets for all
    BlueField SoCs:
    struct mlxbf_i2c_resource *timer;
    struct mlxbf_i2c_resource *mst;
    struct mlxbf_i2c_resource *slv;
    
    Of course, all offsets had to be adjusted accordingly, and we took
    this chance to reorganize the macros depending on the register block
    they target.
    
    There are only 2 registers' offsets that do not fit within this
    schema so their offsets are passed as SoC-specific parameters:
    smbus_master_rs_bytes_off
    smbus_master_fsm_off
