Subject: [PATCH] wifi: ath12k: correct the data_type from QMI_OPT_FLAG to QMI_UNSIGNED_1_BYTE for mlo_capable

Currently, the encoding rule for field mlo_capable in struct
qmi_wlanfw_host_cap_req_msg_v01 defined in array
qmi_wlanfw_host_cap_req_msg_v01_ei uses type QMI_OPT_FLAG.

Unfortunately, all ath12k firmware actually expects this field to be of
type NON QMI_OPT_FLAG such as QMI_UNSIGNED_1_BYTE/QMI_UNSIGNED_8_BYTE...
And as a result, firmware is unable to correctly decode the mlo_capable
field.

Change the ath12k definition as QMI_UNSIGNED_1_BYTE to match the firmware
definition so that firmware can correctly parse the mlo_capable info from
message QMI_WLANFW_HOST_CAP_REQ_V01 at wlan load time.

This is just an accidental typo and that both WCN7850 and QCN9274 firmwares
use QMI_UNSIGNED_1_BYTE.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4
