The two functions riscv_intc_aia_irq() and riscv_intc_irq()
are only called by C functions.

Hi riscv maintainers and all,

Related question:

I believe the asmlinkage in riscv is a nop, is it OK to
remove asmlinkage from all riscv code?

Anyway, no matter what will be the decision, it's correct to
remove asmlinkage in riscv intc driver as this patch does.

thanks
