A most basic PSCI implementation with only one psci_version is added for
LS1043A, this can verify the generic PSCI framework, and more platform specific
implementation will be added later.

Oops.
I did remove this generic PSCI for LS platform since we have our
specific PPA, but that change wasn't included at last, I'll update
this.

Yes, C code is better and even necessary for some cases.
Drawback of assemble language is that it is difficult not only for
developers but also for the reviewers and maintainers.
I am implementing our NXP/Freescale LS1 platform's system-suspend
function, it is written in C too, is is impossible wit
my later 7/11 patch, Andre raised his comments about dt too, but
