Use the environment variable armv8_switch_to_el1 to determine whether to switch to EL1 at runtime. This is an alternative to the CONFIG_ARMV8_SWITCH_TO_EL1 compile-time option.
The environment variable will be ineffective if the ARMV8_MULTIENTRY config is used.
This is required by the Armv8r64 architecture, which must be able to boot at S-EL1 for Linux but may need to boot at other ELs for other systems.

Applied to u-boot/next, thanks!
