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
