hw/core/or-irq: Increase limit of or-lines to 48

qemu with hax to log dma reads & writes jcs.org/2018/11/12/vfio

Exynos DMA requires up to 33 interrupt lines (32 event interrupts
plus abort interrupt), which all need to be wired together. Increase
the maximum number of or-irq lines to 48 to support this configuration.
