Merge branch 'net-ipa-sc7180-suspend-resume'

Alex Elder says:

====================
net: ipa: sc7180 suspend/resume

This series permits suspend/resume to work for the IPA driver
on the Qualcomm SC7180 SoC.  The IPA version on this SoC requires
interrupts to be enabled when the suspend and resume callbacks are
made, and the first patch moves away from using the noirq variants.
The second patch fixes a problem with resume that occurs because
pending interrupts were being cleared before starting a channel.
