[v3,0/2] spi: pxa2xx: Adjust DMA burst size per platform

Message

On some platforms DMA burst size is not the same as hard coded default.
Fix the driver to support them.

In v3:
- drop threshold print since it's easy to calculate constant (Jarkko)
- split one more unrelated change to a separate patch,
  but independent from this series  (Jarkko)

In v2:
- drop unrelated changes (Jarkko, Robert)
- don't include Robert's tag due to changes in the patch

  spi: pxa2xx: Introduce DMA burst size support
  spi: pxa2xx: Debug print DMA burst size

Forgot to rebase.
It will not compile on v5.1-rc1 due to s/master/controller/g changes.
