arm: zynq defconfig: Remove dmatest

The DMA test code seems to constantly run some processes on
the system. I guess most people don't want this.
So, remove DMA test code from the default configuration.

cpufreq: zynq: remove loops_per_jiffy recalculate for smp

With ARM smp common code recalculating loops_per_jiffy in a cpufreq
transiton notifier call, the loops_per_jiffy recalculate in zynq-cpufreq
driver becomes redundant.  Remove it.

This is the same change as commit 'cpufreq: OMAP: remove loops_per_jiffy
recalculate for smp' (sha1: cd664cc3a574b30988476143c1dcc9298b1fa531)
ported to Zynq.
