[RFC PATCH 0/6] Add SA2UL Public Key Accelerator driver

The PKA is a subdevice of the SA2UL that provides hardware acceleration
for asymmetric cryptography algorithms. RSA and Diffie-Hellman are
enabled in this patch series.

Tested using these configurations:
- CONFIG_CRYPTO_MANAGER_DISABLE_TESTS=n
- CONFIG_CRYPTO_MANAGER_EXTRA_TESTS=y

These patches are RFC for now because we're waiting for legal to clear
us to release the firmware.

The dts patches depend on [1] and [2], respectively, to apply without
fuzz.
