884285bf64 cadence_ttc: Fix 'clear on read' behavior
A missing call to qemu_set_irq() when reading the IRQ register
required SW to write to the IRQ register to acknowledge an
interrupt. With this patch the behavior is fixed:
 - Reading the interrupt register clears it and updates the timers
   interrupt status
 - Writes to the interrupt register are ignored

Change the timer clock frequency to 133MHz which is correct. the old 2.5MHz
value was for the pre-silicon emulation platform.
