Merge tag 'arm-soc/for-4.21/devicetree' of https://github.com/Broadcom/stblinux into next/dt

This pull request contains Broadcom ARM-based SoCs Device Tree changes
for 4.21, please pull the following:

- Rafal relicenses a bunch of DTS files he wrote under the GPL 2.0+/MIT
  license and adds proper SPDX license tags in the process

- Rene adds support for the Linksys EA6500 v2 Wi-Fi router based on
  BCM4708 plus two BCM4360 and BCM4331 radios

- Phil documents and updates the vchiq mailbox compatible string in
  order to establish a correct agreement between the Raspberry Pi
  firmware and the ARM CPU's view of what an ARM CPU cache line size is,
  he also fixes the mailbox "reg" property to be correctly expressed in
  bytes

- Stefan updates the Raspberry Pi Zero DTS files to use SPDX tags

- Florian enables the SATA PHY and AHCI controller on the BCM63138 SoCs,
  he also does a bit of refactoring of aliases for the Northstar Plus
  DTS files
