[ Upstream commit a0ffa8115e ]
Masks the "DSP Virtual Mailbox 2 write" interrupt when before
issuing the hibernate command to the DSP. The interrupt is
unmasked when exiting runtime suspend as it is required for
DSP operation.
Without this change the DSP fires an interrupt when hibernating
causing the system spin between runtime suspend and runtime
resume.
