add new acquireTvInputHardware API to allow the clients to pass their

priority hints in

This change is to allow the TunerResourceManager to manage the
TvInputHardware resources.

Changes are needed in the TvInputHardwareManager implementation to
request resource from TRM instead of directly granting resources to the
client.
