gsd4e_v2: finish moving ORG4472 code over to more generic GSD4E code.

- test code for initial testing of the GSD4e based Antenova M10478 gps
  module.

- The M10478 GSD4e chip starts up in SirfBin and no hunting is needed
  (SPI).  Hunting is a hold over from the UART based gps chips with
  changing baud rate.  Remove hunting.

- move GPS{C,P} -> Gsd4e{C,P}, move CHIP_GPS to CHIP_GPS_GSD4E
