This patch updates the el3_arch_init_common macro so that it fully
initialises essential control registers rather then relying on hardware
to set the reset values.

The context management functions are also updated to fully initialise
the appropriate control registers when initialising the non-secure and
secure context structures and when preparing to leave EL3 for a lower
EL.

This gives better alignement with the ARM ARM which states that software
must initialise RES0 and RES1 fields with 0 / 1.

This patch also corrects the following typos:

"NASCR definitions" -> "NSACR definitions"

This patch uses the U() and ULL() macros for constants, to fix some
of the signed-ness defects flagged by the MISRA scanner.

This patch re-factors the following headers to make it easier to
integrate the PSCI library with an AArch32 Secure Payload :

  *  bl_common.h : The entry point information and the param
     header data structures are factored out into separate
     headers ep_info.h and param_headers.h
  *  psci.h : The PSCI library interfaces are factored out
     into the new header psci_lib.h
  *  context_mgmt.h : The header file is modified to not include
     arch.h when compiled for AArch32 mode.

No functional changes are introduced by this patch.
