irqchip/riscv-intc: Fix low-level interrupt handler setup for AIA
Use riscv_intc_aia_irq() as the low-level interrupt handler instead of the
existing riscv_intc_irq() default handler to make demultiplexing work
correctly.
Also print "using AIA" in the INTC boot banner when AIA is available.
Fixes: 3c46fc5b5507 ("irqchip/riscv-intc: Add support for RISC-V AIA")
