wcnss: Indicate calibrated data availability

Before triggering WCNSS platform driver, indicate thru a /sys parameter
that calibrated data is available at user space. So platform driver
should wait for the Android daemon to transfer this data; and then
download this data to WCNSS. This change also removes the support for
loading WCNSS platform driver as DLKM.
