[PATCH v2 00/30] mci: imx-esdhc: add HS200 support

[Ahmad Fatoum]

On my i.MX8MP board this increases sequential read nearly from
72 MiB/s to 131 MiB/s.

I also got HS400ES running, but it gives me occasional CRC errors, so
this series only concerns itself with HS200 for now.

v1 -> v2:
  - use correct speed comparison in commit message. v1 had KASAN
  and DMA_API_DEBUG enabled..
  - define and use new sdhci_compute_timeout helper (Sascha)
  - remove superfluous comment about clearing bits (Sascha)
  - always populate delay settings in boarddata (Sascha)
  - reduce number of Linux SDHCI quirks mentioned in commit
    message to 51 (Sascha)
