qcacld-3.0: Add new config flag CONFIG_MULTI_CHIP_SUPPORT

For targets that support multiple chipsets, symbols are getting
exported for all supported chipsets, causing wlan driver to
occasionally not load upon bootup. In order to not have symbols
exported for multiple chipsets, add new config flag
CONFIG_MULTI_CHIP_SUPPORT to disable exporting symbols for targets
that support multiple chipsets.
