This series adds 1-bit bus width support for sdhci-esdhc-imx driver.

Currently sdhci-esdhc-imx doesn't support 1-bit width because it
doesn't call sdhci_get_property() to parse "bus-width = <1>" and
set SDHCI_QUIRK_FORCE_1_BIT_DATA quirk.

After adding sdhci_get_property(), another issue is exposed:
mmc_select_hs200() returns 0 without switching when 1-bit bus is
used, causing mmc_select_timing() to skip mmc_select_hs(). This
leaves eMMC in legacy mode (26MHz) instead of High Speed (52MHz).

Fix by dropping incompatible UHS/DDR/HS200/HS400 caps in
sdhci_setup_host() for 1-bit width, and clean up duplicate code now
handled by common framework.

Luke Wang (4):
  mmc: sdhci: fix timing selection for 1-bit bus width
  mmc: sdhci-esdhc-imx: add 1-bit bus width support
  mmc: sdhci-esdhc-imx: remove duplicate HS400 bus width validation
  mmc: sdhci-pltfm: remove duplicate DTS property parsing
---
Changes in v3:
- Keep SDHCI_QUIRK2_CAPS_BIT63_FOR_HS400 check for SDHCI_SUPPORT_HS400
Changes in v2:
- Moved fix from mmc_validate_host_caps() to sdhci_setup_host()
