Subject: [PATCH] perf: omap3/omap4: enable OMAP3_EMU to support perf

See the below dependency:

	config CPU_HAS_PMU
	        depends on (CPU_V6 || CPU_V6K || CPU_V7 || XSCALE_PMU) && \
	                   (!ARCH_OMAP3 || OMAP3_EMU)
	        default y
	        bool

so we have to enable OMAP3_EMU that CPU_HAS_PMU can be selected to
make pmu.o built into kernel, then perf is supported on omap3 and omap4.

No doubt, perf may work well on omap3 based board. For omap4, perf still
does work with the patches:

	http://lists.infradead.org/pipermail/linux-arm-kernel/2011-March/045283.html

LP#702999 have some kind of track about this.
