LF-6118-2: arm: dts: imx6sx: Add entropy delay property
Add imx6sx entropy-delay property.
TRNG self test are run to determine the correct entropy delay.
firmware test is executed with different voltage and temperature to
identify the worst case value for entropy delay. after adding a margin
value(1000),entropy delay should be at least 12000.
