i.MX6SX: crypto/fsl: fix entropy delay value

RNG Hardware error is reported due to incorrect entropy delay

rng self test are run to determine the correct ent_dly.
test is executed with different voltage and temperature to identify the
worst case value for ent_dly. after adding a margin value(1000),
ent_dly should be at least 12000.
