[PATCH 2/3] arm: pmu: support pmu irq routed from CTI

Hi,

Subject: [PATCH 2/3] arm: pmu: support pmu irq routed from CTI

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

This patch introduces pmu_platform_data struct to
support pmu irq routed from CTI, such as implemented
on OMAP4.

Generally speaking, clearing cti irq should be done in
irq handler, also enabling cti module after calling
request_irq and disabling cti module before calling
free_irq.

This will conflict with the the ux500 PMU workaround:
