[PATCH] arm: imx: Remove arch_env_get_location to fix env lockdown

[Abdelrahman Ibrahem]

This patch resolves an issue encountered with Layerscape SoCs, where
attempts to restrict write access to environment variables to enforce
secureboot are ineffective when using the CONFIG_ENV_IS_NOWHERE
configuration in combination with CONFIG_ENV_IS_IN_xxx.
