Update the fifo code to use the HALs exposed by "Top" unit to read data from device_info table. The information for GRAPHICS engine in device_info table is now parsed using the get_device_info HAL from "Top" unit. Copy engine(CE) has multiple entries in the device_info table corresponding to each instance of the engine. Prior to Pascal, each instance of an engine was denoted by different engine type. For example in GM20B, there are engine types like COPY_ENGINE0, COPY_ENGINE1 and so on. In Pascal and chips beyond, a new field called "inst_id" is added and the engine_type is kept the same for different instances of an engine. For example in GP10B, all copy engine entries have same engine type i.e ENGINE_LCE, but different inst_ids. So for Pascal and chips beyond, we use a different HAL to get CE information from device_info table.
