IOCTL timeout while bring up WI-FI on RT1160/1170.

Hello

Trying to bring WI-FI on RT1160/1170 over SDIO but i am facing IOVAR timeout issue from the wi-fi driver(CMD53 BLOCK FAIL)

I traced and found that below function from sdmmc is causing for the same.

USDHC_TransferNonBlocking(host->hostController.base, &host->handle, &dmaConfig, content);

Returning with the below log:

SDMMCHOST_TransferFunction data fail event : 9

Above issue occurs after firmware and nvram file download and the first iovar call.

I have tried debugging with below changes but issue is still occurs.
SDIO speed changing.
IOCTL timeout increased.

Can you please help in solving this issue or let me know if there any flags/settings need for the RT1160/1170 for wi-fi bring up.
