MAINTAINERS: remove obsolete file entry in DIALOG SEMICONDUCTOR DRIVERS

Commit 6277a486a7fa ("regulator: dt-bindings: Convert Dialog DA9211
Regulators to DT schema") converts the last txt dt-binding in DIALOG
SEMICONDUCTOR DRIVERS to the yaml format. With that, there is no file,
which matches the pattern for the dt-binding txt file entry in that
section. The existing yaml files are already covered by the file entry with
the pattern dlg,da9*.yaml.

Remove the obsolete file pattern in DIALOG SEMICONDUCTOR DRIVERS.
