boot/mv-ddr-marvell: disable SSP

Browse Source 
Add a patch to disable SSP. The toolchain enables SSP by default when
one of BR2_SSP_ options is enabled. But ATF code for the Marvell
platform does not provide the required low level routines. This leads to
link time failure.

Subject: [PATCH] Makefile: disable stack protection
The Buildroot toolchain might enable stack protection by default. That
breaks linking because ATF does not provide the required __stack_chk
routines.
The mv-ddr-marvell Makefile provides no way to add custom CFLAGS. Patch
Makefile to disable stack protection.
