ARC: [intc-*] switch to linear domain
Now that we have Timers probed from DT, don't need legacy domain This however requires mapping to be called explicitly for the IRQ which still can't (and probably never) be probed from DT such as IPI and SOFTIRQ Acked-by: Marc Zyngier <marc.zyngier@arm.com> Signed-off-by: Vineet Gupta <vgupta@synopsys.com>
