Merge tag 'arm-soc/for-5.20/soc' of https://github.com/Broadcom/stblinux into arm/soc

This pull request contains Broadcom SoC drivers changes for 5.20, please
pull the following:

- Miaoqian fixes a device_node reference count leak in the Kona SMC
  initialization code

- William moves the 63138 support code to use CONFIG_ARCH_BCMBCA which
  is how all of those similar SoCs from the BCA division are supported
  moving forward. This includes machine code and UART low-level debug
  code.

* tag 'arm-soc/for-5.20/soc' of https://github.com/Broadcom/stblinux:
  ARM: debug: bcmbca: Replace ARCH_BCM_63XX with ARCH_BCMBCA
  arm: bcmbca: Add BCMBCA sub platforms
  arm: bcmbca: Move BCM63138 ARCH_BCM_63XX to ARCH_BCMBCA
  ARM: bcm: Fix refcount leak in bcm_kona_smc_init
