MAINTAINERS: update entries affecting VIA Technologies

Since the original maintainer-Joseph Chan (josephchan@via.com.tw) doesn't
handle the Linux driver for VIA now, I would like to request to update the
maintainer for the SD/MMC CARD CONTROLLER DRIVER and VIA
UNICHROME(PRO)/CHROME9 FRAMEBUFFER DRIVER before we find a better one.
