serial: Properly spell out the structure member names of serial_driver

Properly spell out the whole structure member names when an initialized
varible is instantiated from the struct serial_driver. In case the
structure definition for struct serial_driver undergoes reordering,
there will be no impact on variables defined based on this structure.
