The intermediate hash values generated during an update task were handled incorrectly in the driver. The values have a defined format for each algorithm. Copying and pasting from the HASH_RESULT register balantly would not work for all the supported algorithms. This incorrect handling causes failures when there is a context switch between multiple operations. To handle the expected format correctly, add a separate buffer for storing the intermediate results for each request. Remove the previous copy/paste functions which read/wrote to the registers directly. Instead configure the hardware to get the intermediate result copied to the buffer and use host1x path to restore the intermediate hash results.
