Subject: [019/104] ARM: OMAP2: select ARM_AMBA if OMAP3_EMU is defined

3.1-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ming Lei <tom.leiming@...il.com>

commit a8a6565c7615cab3608d75af95b5c8a3522cd7c4 upstream.

This patch selects ARM_AMBA if OMAP3_EMU is defined because
OC_ETM depends on ARM_AMBA, so fix the link failure[1].
