[PATCH v3 00/12] Add SiFive TMC0 and SMC0 driver

[Nick Hu]

The previous version can be found in [1].

SiFive TMC0 and SMC0 are the power controllers that controls the Tile and
CoreComplex power domain. Add the drivers to support the power
management features such as HSM STOP and System Suspend.

Some features, such as power management, may require flushing the entire
cache before entering a non-retention power state. To support this, a
simple cache framework is introduced to allow the external CMO to
perform a full cache flush.

Changes in v3:
- Add the SiFive TMC and SMC driver

Changes in v2:
- Since the platform override hooks was deprecated, use the fdt_driver
for initializing the sifive_dev_platform.
