qcacld-3.0: Update prefix for multi-interface with chip name

1. The paths for driver to get ini and fw files
   are incorrect for QCA SDIO chip on Dual-WiFi
   platforms, with wrong prefix or no prefix.
   Correct prefix for ini file, from '<mod_name>'
   to '<chip_name>/'; add prefix '<chip_name>/'
   for fw files.

2. For QCA9377, there is a special cnss API for getting
   fw names, it's cnss_get_qca9377_fw_files().
   Use the right cnss API to get fw files for QCA9377
