MAINTAINERS: mmc: take over as maintainer of MCI & SDHCI MICROCHIP DRIVERS

On the one hand Eugen has taken responsibilities outside Microchip, on the
other hand I have some experience with the Microchip SDMMC SDHCI
controller. Change Eugen as reviewer and take over maintainership of the
SDHCI MICROCHIP DRIVER. Also, take over maintainership of its predecessor,
that is the MCI MICROCHIP DRIVER.
