MAINTAINERS: repair reference in HYCON HY46XX TOUCHSCREEN SUPPORT

Commit aa2f62cf211a ("Input: add driver for the Hycon HY46XX touchpanel
series") adds the file ./drivers/input/touchscreen/hycon-hy46xx.c, but the
file entry in MAINTAINERS refers to ./drivers/input/touchscreen/hy46xx.c.

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

  warning: no file matches    F:    drivers/input/touchscreen/hy46xx.c

Repair the file entry by referring to the right location.
