ARM: fix LTO for seaboard 

When seaboard_defconfig is compiled with LTO, the compiler complains
about some instructions not being supported in ARM mode.

This is caused by arch/arm/mach-tegra/tegra20/warmboot_avp.c having
different CFLAGS declared in Makefile. This file needs to be compiled
without LTO.

Fix this by removing -flto for this file.
