Re: [PATCH v2] mmc: sdhci-brcmstb: add cqhci suspend/resume to PM ops

cqhci timeouts observed on brcmstb platforms during suspend:
   ...
   [  164.832853] mmc0: cqhci: timeout for tag 18
   ...

Adding cqhci_suspend()/resume() calls to disable cqe
in sdhci_brcmstb_suspend()/resume() respectively to fix
CQE timeouts seen on PM suspend.

Fixes: d46ba2d17f90 ("mmc: sdhci-brcmstb: Add support for Command Queuing (CQE)")
