From: Lingling Xu <ling_ling.xu@xxxxxxxxxx>
Because cpu_relax() takes different time on different SoCs, for some rare
cases, it would take more than 1000 cycles for waitting load operation
finished. The result of many times testing verified that changing the
timeout value to 2000 can solve the issue.
