MA-6580 recovery.img cannot be authenticated by HAB
Remove the authentication size to be a fixed size, due to
recovery.img may be much bigger than the boot.img
Add signature size to boot or recovery image size, which is
added by boot_signer in android build process
Signed-off-by: guoyin.chen <guoyin.chen@freescale.com>
(cherry picked from commit d59b24fefcd56d085c4010643ca9f6522a3cc58a)
