ath12k: big endian bringup

Hello devs,
I need help to bring up the QCN9274 with ath12k driver on big endian PowerPC
platform. I've already found some issues and fixed the MHI start procedure [1]
and QMI conversion [2]. Furthermore I added some endianness fixes on 'qmi.c'
file and could successfully transfer the firmware and boardfile to the wireless
module. But the firmware does not start properly.
I'm trying to analyze the error and don't fully understand what is happening.
While 'ath12k_htc_connect_service' I expect a successful response from
'ath12k_htc_send', but the connection then is timeout. It seems that I should
receive a message with length of 20 and at least I get one. But then the driver
remains endless in the 'ath12k_ce_recv_process_cb' and I always get a message of
length 0 from the 'ath12k_hal_ce_dst_status_get_length' until RCU stall happens.
More interesting is the 'CE_ATTR_BYTE_SWAP_DATA' from ath11k, that is still used
in ath12k code, but HAL structures now are swapped in driver itself at the same
time. Is that correct?
Please, if anyone could give me a hint, what do I need to look for to fix the
problem? Here are the logs with ATH12K_DBG_ANY level:
