Masahiro Yamada 1d2c0506d3 mmc: move more driver config options to Kconfig
Move (and rename) the following CONFIG options to Kconfig:

  CONFIG_DAVINCI_MMC  (renamed to CONFIG_MMC_DAVINCI)
  CONFIG_OMAP_HSMMC   (renamed to CONFIG_MMC_OMAP_HS)
  CONFIG_MXC_MMC      (renamed to CONFIG_MMC_MXC)
  CONFIG_MXS_MMC      (renamed to CONFIG_MMC_MXS)
  CONFIG_TEGRA_MMC    (renamed to CONFIG_MMC_SDHCI_TEGRA)
  CONFIG_SUNXI_MMC    (renamed to CONFIG_MMC_SUNXI)

They are the same option names as used in Linux.

This commit was created as follows:

[1] Rename the options with the following command:

find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '
s/CONFIG_DAVINCI_MMC/CONFIG_MMC_DAVINCI/g
s/CONFIG_OMAP_HSMMC/CONFIG_MMC_OMAP_HS/g
s/CONFIG_MXC_MMC/CONFIG_MMC_MXC/g
s/CONFIG_MXS_MMC/CONFIG_MMC_MXS/g
s/CONFIG_TEGRA_MMC/CONFIG_MMC_SDHCI_TEGRA/g
s/CONFIG_SUNXI_MMC/CONFIG_MMC_SUNXI/g
'

[2] Commit the changes

[3] Create entries in driver/mmc/Kconfig.
    (copied from Linux)

[4] Move the options with the following command
tools/moveconfig.py -y -r HEAD \
MMC_DAVINCI MMC_OMAP_HS MMC_MXC MMC_MXS MMC_SDHCI_TEGRA MMC_SUNXI

[5] Sort and align drivers/mmc/Makefile for readability
