Mark as experimental for now until we get closer to production
to avoid possible undesireable behavior when mixing newer
boards with older kernels.

If SOC doesn't expose dedicated vram, discovery region may be

generic read_binary_from_mem and add a fallback path to read from system

Add function to initialize soc configuration information for GC 9.4.3

configuration information is available through discovery.
For GC9.4.3 compute partition related callbacks are initialized as part

Truncate the 64bit base address from ip discovery and only store lower 32bit
ip base in reg_offset[].
Bits > 32 follows ASIC specific format, thus just discard them and handle it
within specific ASIC.
By this way reg_offset[] and related helpers can stay unchanged.

Since commit ee6d3dd4ed ("driver core: make kobj_type constant.")
the driver core allows the usage of const struct kobj_type.
Take advantage of this to constify the structure definitions to prevent
