[BOOT-WRAPPER 00/11] Cleanup initialization

[Mark Rutland]

These patches cleanup the boot-wrapper initialization logic to make it
more consistent and easier to extend in C code in future. The big
changes are:

* The kernel is always entered via an exception return. This allows us
  to initialize PSTATE consistently, and will allow us to adjust the
  SPSR dynamically in C code in future if necessary.

* Regardless of the entered exception level, CPU state is initialized
  under cpu_init_arch(), allowing for logic to be shared regardless of
  which exception level was entered.

* CPUs are initialized sequentially, which allows better for better
  logging within the boot-wrapper.

Mark.
