[PATCH v9 2/9] gpu: nova-core: require DmaObject on FalconDmaLoadable, not FalconFirmware

[Alexandre Courbot]

Not all firmware is necessarily loaded through DMA: the PIO loading
method does not require shared memory between the CPU and GPU. Thus,
move the requirement to dereference to a DMA object from
`FalconFirmware` to the mode accurate `FalconDmaLoadable`.
