qemu-armv7: Minimal changes to pass compiling qemu-v7 platform.

The ARM configuration files have been changed that we need more settings to run
Coreboot on qemu-v7.

Also fixed the incorrect Makefile settings that caused armv7 to try building
with armv8 cache.

BRANCH=none
BUG=none
TEST=make menuconfig # select qemu-armv7
     make # pass
     qemu... # successfully boots to ramstage.
