Public bug reported:

Provide firmware update for PKA HW.
This new firmware adds support for Curve 25519 and Curve 448.

SRU Justification:

[Impact]
* Currently, curve 25519 and 448 are not supported by PKA firmware, new 
firmware adds this support.

[Fix]
* Update PKA firmware image "pka: Update firmware"

[Test Case]
* If there is any issue with the new firmware, PKA driver will fail to load.
Hence, on bootup, check if the PKA linux driver is loaded without any errors.
Ex:# dmesg | grep -i pka.

[Regression Potential]
* PKA HW might fail to operate as expected due to the new firmware image.
This can be verified by performing a validation test.
Ex:# /usr/lib/aarch64-linux-gnu/libpka1/pka_test_validation -c 1 -r 1 -s 0
........
........
        tests_passed=60 
        tests_failed=0 
        total_tests=60  
validation tests passed!
