wifi: ath12k: handle REO CMD ring for QCC2072

As far as REO CMD ring is concerned, there are two differences between
QCC2072 and the existing chips:

For the first, the TLV header of ring descriptor for QCC2072 is 32 bits
while 64 bits for existing chips.

For the second, QCC2072 has different hal_reo_get_queue_stats,
hal_reo_flush_cache and hal_reo_update_rx_queue structures. Take
hal_reo_get_queue_stats as an example:

QCC2072:
struct hal_reo_get_queue_stats_qcc2072 {
        struct hal_reo_cmd_hdr cmd;
        [...]
        __le32 rsvd0[6];
} __packed;

QCN9274/WCN7850:
struct hal_reo_get_queue_stats {
        struct hal_reo_cmd_hdr cmd;
        [...]
        __le32 rsvd0[6];
        __le32 tlv64_pad;
} __packed;

Note there is no tlv64_pad at the end for QCC2072, but all other
former fields share the same layout.

These make different ring entry size, so that parameter has to be updated
with respect to existing chips. This is done in the newly introduced
ath12k_hal_srng_create_config_qcc2072() function, which first creates all
ring configs by utilizing ath12k_hal_srng_create_config_wcn7850() and then
updates the individual field.

Besides, the REO command TLV encoding also need to be corrected because of
the different TLV bits. This is done by introducing a 32 bit variant for
each of the existing 64 bit callback.

Note the hal_reo_get_queue_stats_qcc2072 structure is introduced for the
purpose of calculating ring entry size. Existing hal_reo_get_queue_stats
structure gets used elsewhere even for QCC2072. This is working because
the only difference is the tlv64_pad field that is located at the end and
not getting used, hence can be ignored.
