[U-Boot] [PATCH v5 0/6] Add ARMv8 PSCI framework

[Hongbo Zhang]

v4-v5 changes:
 - rebased to latest u-boot version to ease conflict.
 - added mutually exclusive from FSL_PPA.

v3-v4 changes:
 - Re-added the 1/6 from v2, and move the newly re-named macro into Kconfig
 - Add "Reviewed-by: Tom Rini <trini at konsulko.com>" for patch 4/6 ~ 6/6.

v2-v3 changes:
 - Drop the previous 1/6, since the previous CONFIG_ARMV8_PSCI in common parts
of codes also work for generic PSCI framework, so there are 5 patches in this
iteration.
 - Add "Reviewed-by: Tom Rini <trini at konsulko.com>" for patches 1/5 and 2/5,
which were 2/6 and 3/6.
 - Move config values for ls1043 from armv8/Kconfig to s1043ardb_defconfig.

v1-v2 changes:
 - The new config options are introduced in Kconfig when used for first time
 - Introduce new config options in armv8/Kconfig instead of LS1043 platform
 - Move previous patch 5/6 to current 2/6 place

v1 notes:

This patch set introduces ARMv8 PSCI framework, all the PSCI functions are
implemented a default dummy one, it is up to each platform to implement their
own specific ones.

The first 1/6 patch is a prepare clean up for adding ARMv8 PSCI.
Patches 2/6 to 5/6 introduce new ARMv8 framework and set it up.
The last 6/6 adds a most simple implementation on NXP LS1043 platform, to
verify this framework.

This patch set mainly introduces ARMv8 PSCI framework, for easier review and
merge, further PSCI implementation on LS1043 is coming later.
