hw/timer/cmsdk-apb-dualtimer: Add Clock input
As the first step in converting the CMSDK_APB_DUALTIMER device to the Clock framework, add a Clock input. For the moment we do nothing with this clock; we will change the behaviour from using the pclk-frq property to using the Clock once all the users of this device have been converted to wire up the Clock. We take the opportunity to correct the name of the clock input to match the hardware -- the dual timer names the clock which drives the timers TIMCLK. (It does also have a 'pclk' input, which is used only for the register and APB bus logic; on the SSE-200 these clocks are both connected together.) This is a migration compatibility break for machines mps2-an385, mps2-an386, mps2-an500, mps2-an511, mps2-an505, mps2-an521, musca-a, musca-b1.
