Re-factor header files for easier PSCI library integration
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. Change-Id: I5e21a843c0af2ba8e47dee4e577cf95929be8cd4 Signed-off-by: Soby Mathew <soby.mathew@arm.com>
