[PATCH v2 0/3] Refactor DM IRQ handling

[Aurabindo Pillai]

Changes in V2:
 * fix memory leak.

Interrupts are disabled too early in DM's atomic_commit() which can
cause issues in certain situations with non blocking commits timing
out on flip_done interrupt. The early disabling of interrupts were
necessary due to interrupts accessing crtc state directly. This
refactor removes direct access of crtc state from the irq handler
so that disabling of interrupts can be done later in commit_tail()
