Prior to entry into BL32 we set the SPSR by way of msr spsr, r1.
This unfortunately only writes the bits f->[31:24] and c->[7:0].
This patch updates the bl2 exit path to write the x->[15:8] and c->[7:0]
fields of the SPSR. For the purposes of initial setup of the SPSR the x and
c fields should be sufficient and importantly will capture the necessary
lower-order control bits that f:c alone do not.
This is important to do to ensure the SPSR is set to the mode the platform
intends prior to performing an eret.
