wifi: ath12k: fix scan command endianness on big endian

ath12k_wmi_scan_req_arg stores scan parameters in CPU-native byte order,
while ath12k_wmi_send_scan_start_cmd() writes them into a WMI command
buffer whose contents must be in little-endian format. The existing code
copies the channel list and writes s_ssid and hint_bssid related values to
the command buffer without endian conversion. As a result, scan requests
contain invalid parameters on big-endian systems and fail.

Convert the channel list as well as the s_ssid and hint_bssid related
values to little-endian before writing them to the WMI command buffer. This
preserves the existing behaviour on little-endian systems while fixing scan
requests on big-endian architectures.
