[PATCH v2 6/8] drm/amdgpu: Add PSP public function to load a list of FWs

[Lazar, Lijo]

[AMD Public Use]

v1: Adds a function to load a list of FWs as passed by the caller. This is
needed as only a select need to loaded for some use cases.

v2: Omit unrelated change, remove info log, fix return value when count is 0
