Are you sure that this is the field order you want to choose for Tyr? nova-core
had this order in the past (we're changing this currently), as it came from
OpenRM headers, but it is pretty unusual for datasheets and TRMs, which is also
why the register!() macro examples use the typical and recommended order, i.e.

	pub(crate) GPU_ID(u32) @ 0x0 {
	    /// Architecture major revision.
	    31:28   arch_major;
	    /// Architecture minor revision.
	    27:24   arch_minor;
	    /// Architecture patch revision.
	    23:20   arch_rev;
	    /// Product identifier.
	    19:16   prod_major;
	    /// Major release version number.
	    15:12   ver_major;
	    /// Minor release version number.
	    11:4    ver_minor;
	    /// Status of the GPU release.
	    3:0     ver_status;
	}
