Revert "arm/acpi: Configure SPI interrupt type and route to Dom0 dynamically"

This reverts commit 9d77b3c01d1261ce17c10097a1b393f2893ca657.

The commit is causing a dead loop inside the spinlock function.
spinlocks in Xen are not recursive. Re-acquiring a spinlock that was
already taken by the calling cpu leads to deadlock. This happens
whenever dom0 writes to GICD regs ISENABLER/ICENABLER.

DOM0 writes GICD_ISENABLER/GICD_ICENABLER
  vgic_v3_distr_common_mmio_write()
    vgic_lock_rank()  -->  acquiring first time
      vgic_enable_irqs()
        route_irq_to_guest()
          gic_route_irq_to_guest()
            vgic_get_target_vcpu()
              vgic_lock_rank()  -->  attemping acquired lock
