dt-bindings: trivial-devices: Fix MEMSIC MXC4005 compatible string

The correct name of this chip is MXC4005, not MX4005. This is confirmed
both by the manufacturer website and by the title of the original commit,
which added other MXCxxxx devices as well but only this one misses a "c" in
the compatible string.
