[PATCH] mmc: kconfig: Add CONFIG_SPL_MMC_VERBOSE

[Klaus Heinrich Kiwi]

When building the SPL with MMC config and CONFIG_LOGLEVEL > 7, the
function mmc_select_mode() at drivers/mmc/mmc.c will call
mmc_mode_name() which is only defined if CONFIG_IS_ENABLED(MMC_VERBOSE)
which doesn't have a corresponding CONFIG_SPL_MMC_VERBOSE defined in
Kconfig.

Fixes this build error:

    arm-linux-gnueabi-ld.bfd: drivers/built-in.o: in function
    `mmc_select_mode':

    /drivers/mmc/mmc.c:192: undefined
    reference to `mmc_mode_name'
    make[1]: *** [scripts/Makefile.spl:432: spl/u-boot-spl] Error 1
    make: *** [Makefile:1942: spl/u-boot-spl] Error 2
