Add entropy delay device tree 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 on imx6sx platform, after
adding a margin value(1000),entropy delay should be at least 12000.
- Add dt-bindings
- updated imx6sx device tree
- modify caam driver to read the property
