irqchip: Remove asmlinkage for handlers registered with set_handle_irq()

All architectures with use set_handle_irq() to set the root chip interrupt
handler call that handler from C code, so there's no need for these
handlers to be marked asmlinkage.

Remove asmlinkage for all handlers registered with set_handle_irq().
