wifi: ath12k: handle REO status ring for QCC2072

Browse source 
For QCC2072 below REO status descriptors are different compared with
QCN9274/WCN7850:

        hal_reo_get_queue_stats_status
        hal_reo_flush_queue_status
        hal_reo_flush_cache_status
        hal_reo_unblock_cache_status
        hal_reo_flush_timeout_list_status
        hal_reo_desc_thresh_reached_status

Take hal_reo_get_queue_stats_status as an example:

QCC2072:
struct hal_reo_get_queue_stats_status_qcc2072 {
        __le32 tlv32_padding;
        struct hal_reo_get_queue_stats_status status;
} __packed;

QCN9274/WCN7850:
struct hal_reo_get_queue_stats_status;

Besides, QCC2072 has a 32 bits TLV header while QCN9274/WCN7850 has 64.

This means that there is no difference between these 3 devices in layout
of actual fields, because they all start after a 8 bytes offset

QCC2072:
	{
		struct hal_tlv_hdr tlv;
		__le32 tlv32_padding;
		struct hal_reo_get_queue_stats_status status;
	}

QCN9274/WCN7850:
	{
		struct hal_tlv_64_hdr tlv;
		struct hal_reo_get_queue_stats_status status;
	}

Therefore current implementation luckily works for QCC2072 as well.
However it leads to misunderstanding, which should be avoided.

So add individual REO status ring handling for QCC2072.
