Haotian Zhang 4c4e6ea4a1 gpio: ljca: Fix duplicated IRQ mapping
The generic_handle_domain_irq() function resolves the hardware IRQ
internally. The driver performed a duplicative mapping by calling
irq_find_mapping() first, which could lead to an RCU stall.

Delete the redundant irq_find_mapping() call and pass the hardware IRQ
directly to generic_handle_domain_irq().
