  PM / devfreq: Use lockdep asserts instead of manual checks for locked mutex (2020-05-28 18:02:40 +0900)

----------------------------------------------------------------

Update devfreq for 5.8

Detailed description for this pull request:
1. Update devfreq core
- Use lockdep function for checking mutex state instead of manual checking.
- Replace strncpy with strscpy to fix the compile warning.

2. Update devfreq driver
- Add new imx-bus.c devfreq driver for controlling the bus frequenncy
  and it registers the imx interconnect device which indicates the imx-bus.c
  as the parent device. This relation make the connection between imx-bus.c
  and imx interconnect nodes. In result, the imx-bus.c devfreq driver handles
  the DEV_PM_QOS_MIN_FREQUENCY requirements from imx interconnect nodes
  in order to support the minimum bus bandwidth of interconnect nodes.

- Delete unneed error message and update the boosting on tegra30-devfreq.c.
