Hi Chin,

The PLL settings are copied from previous version http://git.rocketboards.org/u-boot-socfpga.git,

Let's not change this as we are using mainpll for QSPI clock. Besides
that, the QSPI perpll will yield 500MHz which exceed the 400MHz max
clock.

Thanks
Chin Liang

OK, I will restore CONFIG_HPS_PERPLLGRP_PERQSPICLK_CNT as 511

Thanks ShengjiangWu
