Subject: [PATCH v2 0/6] crypto: stm32 hash - reuse for Ux500

By taking some small portions of the Ux500 HASH driver and
adding to the STM32 driver, it turns out we can support both
platforms with the more modern STM32 driver.

The STM32 driver is more modern and compact thanks to using
things like the crypto engine.

We add a polled mode since the Ux500 does not have any
interrupt. Incidentally, this could perhaps be re-used to
implement synchronous mode, if this is desireable.

Changes in v2:
- Use an else-clause in the DT bindings.
- Fix up issues pointed out by Lionel in the driver extension.
- Dropped the patch converting dma_mode to a bool after
  Lionel explained how this works.
- Link to v1: https://lore.kernel.org/r/20221227-ux500-stm32-hash-v1-0-b637ac4cda01@linaro.org
