Hi Mark,
Looks like last two patches in last series posted were missed, so I am
resending this

While going to suspend, if we have any pending D0i3 work scheduled,
flush that and force the DSP to goto D0i3 mode before going to suspend.

We were invoking pci_disable_device() while going to suspend-to-idle and
pci_enable_device() while coming back to active state.
Turns out that we do not need these calls as we only need system to be
wake capable when in suspend-to-idle state. The wake capability is
already done by enable_irq_wake() calls, so remove these unwanted calls
in driver.

Please allow a reasonable time for review. More complex and less well
explained patches are going to take longer to review.

Sure thing, I somehow though these were missed, so resent just to be sure...
