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.
