MAINTAINERS: drop obsolete file pattern in SDHCI DRIVER section

Commit 5c67aa59bd8f ("mmc: sdhci-pci: Remove dead code (struct
sdhci_pci_data et al)") removes ./include/linux/mmc/sdhci-pci-data.h;
so, there is no further file that matches 'include/linux/mmc/sdhci*'.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains:

  warning: no file matches    F:    include/linux/mmc/sdhci*

Drop this obsolete file pattern in SECURE DIGITAL HOST CONTROLLER
INTERFACE (SDHCI) DRIVER.
