No reason to keep custom handle_loongarch_irq, and move to the generic
one. No reason to keep custom handle_loongarch_irq, and move to the
generic one. The patch also the fixup HAVE_CONTEXT_TRACKING_USER
feature, because handle_loongarch_irq missed ct_irq_enter/exit.
Fixes: 0603839b18f4 ("LoongArch: Add exception/interrupt handling")
