Merge tag 'ux500-v5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into arm/soc

This is a slew of Ux500 updates for the v5.4 kernel cycle:

- Stop populating the PRCMU devices from the core CPU
  file, it works just fine at device_initcall() level.

- Add a missing of_node_put() in the core file.

- Simplify the debug UART code.

- Add myself to MAINTAINERS

* tag 'ux500-v5.4-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  MAINTAINERS: add soc/ux500
  ARM: ux500: simplify and move debug UART
  ARM: ux500: add missing of_node_put()
  ARM: ux500: Stop populating the PRCMU devices early
