qcacld-3.0: Support one MSI vector dynamically

In some platform IRQ allocation may be failed because it can't support
so many MSI vectors. Driver can't be loaded in this platform.

Implement one MSI vector dynamic support. MSI vector number is defined
in platform driver, so add platform API to show whether platform is in
one MSI vector mode or not.
