This happens because the AHUB clock rate is too low and it shows 9.83MHz on boot. The maximum rate of PLLA_OUT0 is 49.152MHz and is used to serve I/O clocks. It is recommended that AHUB clock operates higher than this. Thus fix this by using PLLP_OUT0 as parent clock for AHUB instead of PLLA_OUT0 and fix the rate to 81.6MHz.
