[PATCH v7 02/10] spl: make CMD_BOOTZ exclusive with TI_SECURE_DEVICE

[Anshul Dalal]

In the secure OS_BOOT spl execution code path, CMD_BOOTZ enables loading
of a zImage which might allow an attacker to bypass the authenticated
boot with fitImage by replacing it with a malicious image with header
identical to zImage.

Disabling CMD_BOOTZ ensures this code path is never hit inside
spl_parse_image_header.
