Vesnin BMC uses microSD with card presence signal inversion in the
schematics. Add the .read_l callback to detect 'cd-inverted' option
in dts. There is no WP switch, due to this 'disable-wp' also was added
into vesnin dts for sdhci.

Ivan Mikhaylov (3):
  aspeed: dts: add sd card for vesnin
  mmc: sdhci-of-aspeed: enable CONFIG_MMC_SDHCI_IO_ACCESSORS
  mmc: sdhci-of-aspeed: add inversion signal presence
