MIPS/Malta: Probe gic-timer via devicetree
The Malta platform is the only platform remaining to probe the GIC clocksource via gic_clocksource_init. This route hardcodes an expected virq number based on MIPS_GIC_IRQ_BASE, which can be fragile to the eventual virq layout. Instread, probe the driver using the preferred and more modern devicetree method. Before the driver is probed, set the "clock-frequency" property of the devicetree node to the value detected by Malta platform code.
