ARM: hisi: enable MCPM implementation
Multiple CPU clusters are used in Hisilicon HiP04 SoC. Now use MCPM
framework to manage power on HiP04 SoC.
Changelog:
v20:
* Disable L2 prefetch when the whole cluster is down.
* Move disabling snoop filter into power_down() after L2 prefetch
disabled.
* Remove delay in wait_for_power_down() after L2 prefetch disabled.
* Add the sleep polling in wait_for_power_down() again since we
need to wait L2 when the cluster is down.
v19:
* Add comments on those delay hacks.
* Update on checking core enabled counts in wait_for_power_down().
v18:
* Fix to release resource in probe().
* Check whether cpu is already up in the process of making cpu down.
* Add udelay in power up/down sequence.
* Optimize on setting relocation entry.
* Optimize on polling status in wait_for_power_down().
* Add mcpm critical operations.
v17:
* Parse bootwrapper parameters in DTS file.
* Fix to use msleep() in spinlock region.
v16:
* Parse bootwrapper parameters in command line instead.
v13:
* Restore power down operation in MCPM.
* Fix disabling snoop filter issue in MCPM.
v12:
* Use wfi as power down state in MCPM.
* Remove wait_for_powerdown() in MCPM because wfi is used now.
