ARM: smp_twd: add runtime registration support
Add support for the new registration interface to smp_twd. Platforms can populate a struct twd_local_timer with MMIO and IRQ resources, and then call twd_local_timer_register() to have the timer registered with the core. Signed-off-by: Marc Zyngier <marc.zyngier@arm.com>
