[U-Boot] [PATCH 03/16] secure boot: rename CONFIG_SECURE_BOOT config option

[AKASHI Takahiro]

The configuration, CONFIG_SECURE_BOOT, is defined multiple times in
different architecture directories for different implementation.
If UEFI secure boot will be added later, it will make things more messy.

So let's rename them, giving each implementation to different
configuration option. CONFIG_SECURE_BOOT still remains in order not to
break existing implicit dependency.
