Rename the variable and add ENV_ prefix, so that all configuration options which are related to environment would have an CONFIG_ENV_ prefix. No functional change. Use ENV_MMC_DEVICE_INDEX to clarify this is the SD/MMC device index, a number, as enumerated by U-Boot. Update the help text accordingly. Signed-off-by: Marek Vasut <marek.vasut+renesas@mailbox.org>
