libpayload: pistachio: fix timer implementation
timer_raw_value must return the number of CPU ticks, and not the time obtained by dividing the ticks by the CPU frequency. The CPU counter is increased at every 2 CPU clocks and therfore the number of ticks will be the counter value multiplied by 2. BUG=chrome-os-partner:31438 TEST=tested on Pistachio FPGA; it works properly.
