Version 2.4.2 uses native Zephyr __nocache attribute for automatedly generating
noncacheable regions. These attributes are used for the entropy-related buffers
in the CAAM driver.

I strongly suggest using same code for both MCUX SDK and Zephyr, this can keep the source sync and maintain easy.

I made changes which should be compatible with SDK and Zephyr. Made changes in the SDK, and just copied the changes to this PR.
