[ARM] config: enable HAVE_DEFAULT_NO_SPIN_MUTEXES
There was a change introduced in K32 to optimally spin inside the
mutex-lock implementation. This in-turn caused a regression and
manifested as a soft-lockup in kernel while running mulit-media stress
test.
By enabling this config, we are disabling the newly introduced change.
