commit 76a95bd8f9e10cade9c4c8df93b5c20ff45dc0f5 upstream.
When ccree driver runs it checks the state of the Trusted Execution
Environment CryptoCell driver before proceeding. We did not account
for cases where the TEE side is not ready or not available at all.
Fix it by only considering TEE error state after sync with the TEE
side driver.

crypto: ccree - add function to handle cryptocell tee fips error2019-04-25T07:38:16+00:00Ofir Drangofir.drang@arm.com2019-04-18T13:39:09+00:00urn:sha1:897ab2316910a66bb048f1c9cefa25e6a592dcd7
Adds function that checks if cryptocell tee fips error occurred
and in such case triggers system error through kernel panic.
Change fips function to use this new routine.
