Merge tag 'arm-soc/for-5.1/drivers' of https://github.com/Broadcom/stblinux into arm/drivers

This pull request contains Broadcom ARM/ARM64/MIPS based SoCs changes
for 5.1, please pull the following:

- Stefan updates the BCM2835 SoC driver with downstream properties and
  uses that to implement a reboot notifier to tell the VC4 firmware when
  Linux on the ARM CPU is rebooting

- Eric adds a proper power domain driver for the BCM283x SoCs and
  updates a bunch of drivers to have a better and clearer Device Tree
  definition to support power domains/breaking up of functionality. This
  requires converting the existing watchdog driver into a MFD and then
  breaking up the functionality into separate drivers and finally
  updating the DTS files to leverage the power domains information.

- Wei provides a fix for making a symbol static
