media: MAINTAINERS: correct entry in Amlogic GE2D driver section

Commit aa821b2b ("media: MAINTAINERS: Add myself as maintainer of the
Amlogic GE2D driver") introduced a new MAINTAINERS section, but the file
entry points to the wrong location.

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

  warning: no file matches    F:    drivers/media/meson/ge2d/

Adjust the entry to the actual location of the driver.
