irqchip/loongson-pch-pic: Fix translate callback for DT path
In DT path of translate callback, if fwspec->param_count==1
and of_node is non-null, fwspec->param[1] will be accessed,
which is introduced from previous commit bcdd75c596c8
(irqchip/loongson-pch-pic: Add ACPI init support).
Before the patch, for non-null of_node, translate callback
(use irq_domain_translate_twocell()) will return -EINVAL if
fwspec->param_count < 2, so the check in the patch is added.
