The reason for the change is that the register is called System Handler
Priority Register 3 (SHPR3).

When Link Time Optimization (LTO) is enabled, some of the LDR
instructions result in out of range access. The reason is that the
default generated literal pool is too far and not within the permissible
range of 4K.
This commit adds LTORG assembly instructions at required places to
ensure that access to literals remain in the permissible range of 4K.
