[U-Boot] [PATCH] arm: ls102xa: Enable snooping for CCI-400 S0 slave interface
CAAM is connected to CCI-400 S0 slave interface. Disable snooping for S0 will cause CAAM self test failure. This patch is to enable snooping for S0 slave interface.

[Alison Wang] This patch was based on other patch about deep sleep. I will rebase and integrate it into another patch. I will abandon this patch.
Thanks.
