PSCI OS initiated is usually implemented with the extended state id
format, however this does not have to be the case. When this is the
case, the original format will carry the requested power level in
the PowerLevel field. To validate that the requested power state is
valid we must save it so that later when we call
psci_is_last_cpu_to_idle_at_pwrlvl() it checks the right level (instead
of a default 0).
This came up when testing 01959a1656a08dacd1d036d0441165d52bf7563e for
all configurations.

The function always checks the first parent of the current core
instead parse the tree topology to find the parent at parent level
of the CPU. It is because the current loop has no effect as it uses
a fixed parameter 'my_idx' and returns the FIRST parent of CPU.
Also, it looks for the parent nodes in the array of CPU nodes, but
actually they are in a separate array.
This update allows to parse the PSCI topology tree to find
the parent at parent level of the CPU identified by my_idx.
