This converts the following to Kconfig: CONFIG_ARMV8_SWITCH_TO_EL1
As this option isn't enabled anywhere and is for very specific circumstances, it's not an asked Kconfig option and instead noted as something to select.

I think it make sense to be able to enable it via menuconfig to make it selectable based on user wish. I was using it in past to check that we can do clear handoff to EL1 directly.
