hw/timer/xilinx_timer: Use XpsTimerState instead of 'struct timerblock'

This remove a use of 'struct' in the DECLARE_INSTANCE_CHECKER()
macro call, to avoid after a QOM refactor:

  hw/timer/xilinx_timer.c:65:1: error: declaration of anonymous struct must be a definition
  DECLARE_INSTANCE_CHECKER(struct timerblock, XILINX_TIMER,
                           ^
