net/mlx5: Add ONCE and MMIO accessor variants to mlx5_ifc_macros.h
Add MLX5_GET_ONCE / MLX5_SET_ONCE which include READ_ONCE/WRITE_ONCE
semantics for touching ownership bits that hardware may read or write
at any time. The kernel driver doesn't use the IFC struct for these
ownership bits, but the VFIO driver will and needs these helpers.
Add MLX5_GET_MMIO / MLX5_SET_MMIO for accessing the init seg using
the IFC offsets. They embed a readl/writel using the IFC struct to
generate the addressing.
Add MLX5_ARRAY_GET64(), the missing counterpart to
MLX5_ARRAY_SET64().
