omap4.conf: Disable OMAP2 support

When the kernel is built with CONFIG_ARCH_OMAP2 it will select
CPU_V6 and other dependencies which causes issues in user space.
For example when clients try to connect to PulseAudio they will
crash with:
Assertion 'pthread_mutex_unlock(&m->mutex) == 0' failed at pulsecore/mutex-posix.c:108, function pa_mutex_unlock(). Aborting.

Remove support for OMAP2 for now.
