The timer code relies on #defines from mach/iomap.h, cpu_is_*() checks, and a global irq #define. All this makes this file impossible to compile in a mult-target build. Therefore, make a sys_timer struct for each SoC so that machine descriptors can reference the correct timer. Then go through and replace all the defines with raw values that are passed to a common initialization function. This paves the way to adding DT support to this code as well as allows us to compile this file on multiple targets at the same time.
