[v3,7/7] mmc: sdhci-*: Convert drivers to new sdhci_and_cqhci_reset()

Series mmc: sdhci controllers: Fix SDHCI_RESET_ALL for CQHCI |

Commit Message

Brian Norris Oct. 24, 2022, 5:55 p.m. UTC 
  An earlier patch ("mmc: cqhci: Provide helper for resetting both SDHCI
and CQHCI") does these operations for us.

I keep these as a separate patch, since the earlier patch is a
prerequisite to some important bugfixes that need to be backported via
linux-stable.

Signed-off-by: Brian Norris <briannorris@chromium.org>

Changes in v3:
 - Rewrite to new helper, patch sdhci-msm too

Changes in v2:
 - Factor out ->cqe_private helpers
