qcacld-3.0: enable ipa hw dynamic detection capabiliry
MODEM included platform and non-MODEM platform should use
the same binary. Then WLAN cannot disable IPA data path
through INI nor compile time.
WLAN host driver should dynamically detect IPA HW status and
should enable or disable IPA data path based on IPA HW status.
