samples: nrf9160: gnss: integrate with P-GPS partition

Enable using dedicated P-GPS partition instead of
requiring reuse of the MCUboot secondary partition,
by relying on a new P-GPS library default.

If the P-GPS partition in flash is enabled, there is no
need to pass the PM_MCUBOOT_SECONDARY_ADDRESS or _SIZE
to the init function.
