Enable CN63XXP1 errata workarounds

configname: CONFIG_CAVIUM_CN63XXP1

Linux Kernel Configuration
└─>Enable CN63XXP1 errata workarounds
In linux kernel since version 2.6.37 (release Date: 2011-01-04)
The CN63XXP1 chip requires build time workarounds to
function reliably, select this option to enable them. These
workarounds will cause a slight decrease in performance on
non-CN63XXP1 hardware, so it is recommended to select "n"
unless it is known the workarounds are needed.
