Introduce macros to manipulate the SPSR
This patch introduces macros (SPSR_64 and SPSR_32) to create a SPSR for both aarch32 and aarch64 execution states. These macros allow the user to set fields in the SPSR depending upon its format. The make_spsr() function which did not allow manipulation of all the fields in the aarch32 SPSR has been replaced by these new macros. Change-Id: I9425dda0923e8d5f03d03ddb8fa0e28392c4c61e
