Subject: [PATCH] ANDROID: irq: Add vendor data field to struct irq_desc

Add vendor data field to struct irq_desc to track the irq count
growth, vendor module can store the current count value and
calculate the delta in next scan cycle, helpful to enhance irq
performance and debug irq related issues.

This was reverted by commit 263a4f8d5a2c3fda42cdd3fcc1fb622ba3ae2a84
due to merge conflicts, so add it back with the conflicts resolved.
