ti: phc2sys: fix the error/warning messages for -r (REALTIME) optionext/ti-linuxptp-release

This patch removes the error/warning messages triggered by the -r
(REALTIME) option. The following two functions are not applicable to
CLOCK_REALTIME and therefore should not be invoked:
- enable_pps_output()
- enable_extts_input()
