[PATCH v11 0/4] crypto: qce - Split the crypto driver into core and crypto parts

[Bartosz Golaszewski]

With the self-tests fixes queued, we can now split the QCE driver into
the core part necessary to bind to the QCE DT node and enable runtime
power management in order to allow to drop the interconnect votes, and
the crypto part registering the crypto algorithms. The core module is
then enabled in arm64 defconfig while the crypto part stays disabled by
default. 

Merging: Once the fixes to self-tests land in mainline, this series
should be queued through the crypto tree with an immutable branch
provided to ARM-SoC and SoC driver trees (with Acks from SoC
maintainers).

This depends on the final series with fixes for the QCE driver:

- Link to v8: https://patch.msgid.link/20260921-qce-fix-self-tests-v8-0-107537869a72@xxxxxxxxxxxxxxxx

Changes in v8:
- Add a patch making the crypto driver *not* register algos by default
  but only if the user explicitly requests it with the provided module
  parameter
- Use the "offloader" name for the crypto IP instead of "accelerator"
- Fix device module table issues
- Make the core driver use a list (despite it only having a single
  member now) of child auxiliary devices to register to make it clear we
  have the intention of extending this once we start the work on secure
  media playback

  bus, adding the core QCE driver under drivers/soc/ registering the
  auxiliary device and removing the BROKEN Kconfig label

Changes in v6:
- Handle all zero-length HMAC finalizations (like imported state with
  data already hashed), not only the genuinely empty message case
- Add an additional patch addressing the fragmented skcipher payload
  issue
