Merge tag 'imx-fixes-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux into fixes

i.MX fixes for 5.2:
 - A build fix for soc-imx8 driver which needs SOC_BUS support.  To
   avoid dealing with the dependency for every single i.MX SoC bus
   driver, we selects at from architecture level.
 - A fix on i.MX SCU firmware driver to ensure SCU irq is enabled only
   after IPC is ready.
 - A regression fix on cpuidle-imx6sx driver, which causes some
   characters loss on serial communication.

* tag 'imx-fixes-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/shawnguo/linux:
  ARM: imx: cpuidle-imx6sx: Restrict the SW2ISO increase to i.MX6SX
  firmware: imx: SCU irq should ONLY be enabled after SCU IPC is ready
  arm64: imx: Fix build error without CONFIG_SOC_BUS
