Improve timer Resolution on imx28

Hi, this Series increases the timer frequency and decreases min_delta_ns. I saw pretty high max latencies with cyclictest: ~600us. The cause was the min_delta_ns value of 0xf 32kHz clockcycles. But with the 32kHz Clock, the period is still around 30us. So we just increase the clock freqeuncy driv
