arm: ls102xa: Update snoop settings for CCI-400
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. These CCI-400 operations are moved to
board_early_init_f() to be initialized earlier. For S4 slave interface,
issuing of snoop requests and DVM message requests are enabled.
