gpu: nova-core: Use bar1_resource_index() in NovaCoreApi::bar1_size()

bar1_size() reports the length of PCI resource 1 as the size of BAR1.
That is only correct when BAR0 is a 32-bit BAR. On Blackwell, and on some
Ampere GA100 and Hopper SKUs, BAR0 is 64-bit and takes resource slots 0
and 1, pushing BAR1 to slot 2. Slot 1 is then the upper half of BAR0
rather than a BAR of its own, so NOVA_GETPARAM_VRAM_BAR_SIZE reports the
wrong size on those GPUs.

Probe handles this with the new bar1_resource_index(), which it uses to
map BAR1, so use the same lookup here.
