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.
