Older Linux kernels will not properly boot in hyp mode, add support for a bootm_boot_mode environment variable, which can be set to "sec" or "nonsec" to force booting in secure or non-secure mode when build with non-sec support. The default behavior can be selected through CONFIG_ARMV7_BOOT_SEC_DEFAULT, when this is set booting in secure mode is the default. The default setting for this Kconfig option is N, preserving the current behavior of booting in non-secure mode by default when non-secure mode is supported.
