gpu: nova-core: declare unlimited DMA max segment size
The PCI default max_seg_size is 64 KiB. nova-core never raises it, so
mapping the GSP firmware image (~60 MiB) as a scatter-gather table
triggers a DMA-API debug warning when contiguous pages coalesce into
segments that exceed the default:
DMA-API: nova-core 0000:00:03.0: mapping sg segment longer than
device claims to support [len=62914560] [max=65536]
CONFIG_DMA_API_DEBUG=y is required to see this warning.
