MAINTAINERS: Repair file entry in ASPEED USB UDC DRIVER

Commit 055276c13205 ("usb: gadget: add Aspeed ast2600 udc driver") adds
the section ASPEED USB UDC DRIVER with a file entry to aspeed,udc.yaml,
but then, commit 0dde9a46a2cf ("dt-bindings: usb: add documentation for
aspeed udc") actually adds a device tree binding aspeed,ast2600-udc.yaml.

Hence, ./scripts/get_maintainer.pl --self-test=patterns complains about a
broken reference.

Repair the reference to the actually added file in ASPEED USB UDC DRIVER.
