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.

firmware: imx: SCU irq should ONLY be enabled after SCU IPC is ready
arm64: imx: Fix build error without CONFIG_SOC_BUS
