irqchip/gic-v3: Fix selection of partition domain for EPPIs
commit 5f51f803826e ("irqchip/gic-v3: Add EPPI range support") added
GIC_IRQ_TYPE_PARTITION support for EPPI to gic_irq_domain_translate(),
and commit 52085d3f2028 ("irqchip/gic-v3: Dynamically allocate PPI
partition descriptors") made the gic_data.ppi_descs array big enough for
EPPI, but neither gic_irq_domain_select() nor partition_domain_translate()
were updated.
This means partitions are created by partition_create_desc() for the
EPPI range, but can't be registered as they will always match the root
domain and map to the summary interrupt.
Update gic_irq_domain_select() to match PPI and EPPI. The fwspec for
PPI and EPPI both start from 0. Use gic_irq_domain_translate() to find
the hwirq from the fwspec, then convert this to a ppi index.
