ARMv7: PSCI: add PSCI v1.0 functions skeleton
This patch adds all the PSCI v1.0 functions in to the common framework, with
all the functions returning "not implemented" by default, as a common framework
all the dummy functions are added here, it is up to every platform developer to
decide which version of PSCI and which functions to implement.
