gpu: nova-core: read vGPU mode from FSP via PRC protocol
vGPU boot needs to know whether firmware reports vGPU mode as active.
FSP's Management Partition exposes PRC (Product Reconfiguration Control)
as an API for reading device configuration knobs without firmware
updates. The vGPU mode knob is one such configuration value.
Add typed PRC request and response payloads for the vGPU mode object,
add the PRC NVDM type, and parse the returned knob value into VgpuMode.

[ FspPrcMessage is small and short-lived; stack-allocate it instead of
using KBox. - Danilo ]
