mmc: move some SDHCI related options to Kconfig

While I moved the options, I also renamed them so that they are all
prefixed with MMC_SDHCI_.

This commit was created in the following steps.

[1] Rename with the following command
find . -name .git -prune -o ! -path ./scripts/config_whitelist.txt \
-type f -print | xargs sed -i -e '
s/CONFIG_MMC_SDMA/CONFIG_MMC_SDHCI_SDMA/g
s/CONFIG_BCM2835_SDHCI/CONFIG_MMC_SDHCI_BCM2835/g
s/CONFIG_KONA_SDHCI/CONFIG_MMC_SDHCI_KONA/g
s/CONFIG_MV_SDHCI/CONFIG_MMC_SDHCI_MV/g
s/CONFIG_S5P_SDHCI/CONFIG_MMC_SDHCI_S5P/g
s/CONFIG_SPEAR_SDHCI/CONFIG_MMC_SDHCI_SPEAR/g
'

[2] create the Kconfig entries in drivers/mmc/Kconfig

[3] Move the options by the following command
tools/moveconfig.py -y MMC_SDHCI_SDMA MMC_SDHCI_BCM2835 \
MMC_SDHCI_KONA MMC_SDHCI_MV MMC_SDHCI_S5P MMC_SDHCI_SPEAR

[4] Sort drivers/mmc/Makefile for readability
