MAINTAINERS: rectify file pattern in MICROCHIP OTPC DRIVER

Commit 6b291610dd57 ("nvmem: microchip-otpc: add support") adds the
Microchip otpc driver and a corresponding MAINTAINERS section, but slips
in a slightly wrong file pattern.

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

Rectify this file pattern in MICROCHIP OTPC DRIVER.
