icnss2: support to add new flag rproc fw download

Currently wpss_supported variable which helps to download
wlan FW binary using rproc channel and also includes SMP2P
communication between platform and FW.
Currently SMP2P is not required for QCS405 target, Hence
introduced rproc_fw_download to download only wlan FW via rproc.
