Currently, the registers which are maintained per-world, does not
take into account the reset value while configuring the context for
the respective world.
This leads to an issue, wherein the register retains the same value
across world switch, which is an error.
This patch addresses this problem, by configuring the register
(cptr_el3) precisely according to the world, the cpu is in
execution via resetting it before initializing the world specific context.
